Concrete blocks do it yourself. Building blocks: manufacturer do it yourself

Slagoblock is one of the most requested materials for the construction of walls of single-storey buildings. It is characterized by its cheapness and the possibility of independent production at home.

Shlakoblok - wall stone

This construction material Designed for low-rise construction. It is the opinion that if the composition of the knead is to include the cement "high" brand, then from homemade blocks you can make a solid base under a bath or house. but foundation blocks Must withstand huge loads, so blocks should be purchased at the factory, and not to produce yourself.

Slagoblocks are:

• hollow;
• full-tempered.

Due to sufficient strength characteristics, full-scale slag blocks are used for cladding and erection carriers, as well as partitions. At the same time, hollow products have good heat and sound insulation. Due to the voids, raw materials are significantly saved, and therefore the cost of production is much lower.

Also, slag blocks are used as an additional insulation when building frames.

How to make a mortar to create a slag block?

The name of the building materials "Shlakoblock" speaks for itself. This means that the basic component of the solution will be slag obtained in the blast furnace, which should be sifted through a special screen (sieve).

We need:

• 7 parts of the main filler (they will serve the slag);
• 2 shares of gravel having a fraction of 5-15 mm;
• a half of the cement part (it is best to take the brand M 400, 500);
• approximately 3 parts of the water.

In addition to slag, other components can be played as the main element: clay, crushes, sand, gravel, crushed stone, plaster and many others. It should be noted if the domain slag is selected as a filler, then other additives are prohibited. If you want to get a colored slag block, then in the solution you can enter red bricks and brought to small crumbs (they should be extended).

In addition, in the process of producing slag blocks, make sure that the solution does not grow.

Tip for solid blocks: a plasticizer must add to the solution (you can buy it in any building store). Then you will receive not only durable, but also frost-resistant and waterproof blocks.

When you are going to independently establish the process of creating slag blocks, it should be understood that the universal recipe of the solution does not exist. Each master by trial and error picks up its unique formula. If you are a novice, you can resort to standard.

Methods of production of slagoblok

There are two ways to produce such blocks at home.

1. With formwork, that is, forms made of sawn timber or steel sheets.
2. Based on the work of a special machine.

Instructions for independent form making

The design of the form is the following form: Roundyshko and side walls. Between the pair of transverse boards or sheets from the metal follows the distance for you to fix crossbars. Hold the step corresponding to the size of the required slag block.

Since it will be difficult to get the finished product from the form, the design of the container must be collapsible. For the production efficiency, make a formwork designed to receive 4-6 slag blocks.

For the manufacture of a form in order to create slag blocks you will need:

• iron sheets with a thickness of 3 mm;
• iron strips in 5 mm (several pieces);
• cylinders with a diameter of 4 cm;
• welding machine;
• bulgarian;
• chalk for marking.

Stages of manufacturing a single connecting metal form

Step 1. We carry out the marking of the sheet according to the size of the blocks: we will need two longitudinal sides and two transverse. Cut out our plates with a grinder.

The width of the longitudinal plate is 210 mm, length 450 mm, transverse - 210 by 220 mm.

Step 2. The wings should be welded for the slag block to be welded, 3.5 cm high so that the form does not go, and the handle is for the rapid release of the filled solution from the form.

Step 3. According to the contour of the transverse and longitudinal walls, there are notches, in order to hook a form for longitudinally installed walls.

Step 4.. We collect our shape.

Step 5.. To create voids in the slag blast, we make hinged cylinders. They must be welded to a plate with a thickness of 3-4 mm, which should seem to penetrate the cylinders closer to the top. On the end walls of our container we make notches to hook them.

Production of slag blocks with a detachable form

Forms have any dimensions. Standard design sizes 90x190x188 mm, other dimensions can be used in private construction, for example, 40x20x20 cm. In order to save material, it is better to use forms with cells on 4-6 blocks and cylinders (squares) to create cavities.

Metal self-made form (terminal) has the following form.

Consider phased process Making slag blocks.

Step 1. We mix the solution in the concrete mixer.

Step 2. We fall asleep the shovel mixture into our shape. In this case, the mixture is thick. You can also use a liquid solution.

Step 3. Be sure to make sure that the solution filled the capacity evenly. To do this, we will tamper a flooded solution. Control the fillerness of the shape to the edge. Align upper layer With the blade.

Step 4. If the solution is dry, then the special cover should be used, the holes in which will overlap the bayonets in the mold. This device will help to raise our sllacobal. For a liquid solution, such a cover does not apply.

Step 5. We move our block to the open area in order to store further storage. After 30-40 minutes, remove the bottom, side sides and the top cover. To better extract the slag block with the above wall and a longitudinal strip with cylinders with a conventional hammer.

Step 6. For complete drying, we will need no less than a day.

Production of slag blocks using a vibrator machine

Step 1. We mix our solution, given the proportions. Special attention should be paid to the desired amount of water, because the slag blocks should not be spread when you will extract them from the form.

Alsystem

In order to find out the correct consistency of the mixture, swipe a small test. Squeeze the solution in your hand: if it is connected in it, and when falling to the ground is not broken, is a good and correct solution.

Step 2.. Fill our form with a solution, with a slide.

Step 3 . We turn on the machine for 2-4 seconds, after which the loaded composition will be tamped. Rotate the mixture with your hands so that iron pins (cylinders) are visible.

Step 4. If there is not enough mixture in the form, it is necessary to add it, insert clamp and turn the vibrator again. The completion of the formation is evidenced by the sediment of the clamp to the limiters.

Step 5 . Our vibroform should be turned on by 6-10 s.

Step 6 . We close on top with a lid with holes for cylinders. And we make another tamper by raising and lowering the lid 4-5 times.

Step 7 . Then, without turning off the car, the form is removed, it is enough to take the car to myself.

For a shift with vibrator, you can produce up to 500 slag blocks.

Step 8 . Envy blocks 5-10 days. The complete hardening of the obtained building materials is accomplished after the month, the humidity must be high, and the air warm.

Step 9. After a day, blocks can be transferred to the storage location (they will not be broken), but it is all allowed to post them in a week. And if you still be added to the plasticizer solution, then after 6-8 hours they can be moved and stored.

Of course, it is not worth purchasing vibrostanks for a single production, but special attention should be paid to the murmur when creating slag blocks (the quality of the product depends on this process). In this case, it is possible to use the usual grinding vibrator, to which it is enough to put our shape with a mixture.

Features of storage of slagoblok

Store the obtained products in the pyramid stacks, at once a hundred pieces.

At the same time, they stacked with small intervals. You can dry the material for a couple of months, - then you can start building a bath, an extension or a barn.

What are the features of the production of slag block?

In the production of slag blocks, special attention should be paid to drying. So, for example, any dent or irregularity will spoil the building material. Another requirement to the quality of the material is geometry. A large number of Overactions and flaws are a prerequisite for increased costs of decoration of the erected walls. Therefore, that the product is smooth, should be filled with a form or vibroform to the edge. Do not skip the solution with a slide, because the vibration will dying your mixture.

For the best plasticity when the solution is kneading, do not forget to fall asleep the plasticizer in the calculation of 5 g per unit. It will save the product from possible cracks, increase the strength and frost resistance. To build a small bath, it is possible to mix the solution manually, but a concrete mixer will accelerate the process. It is enough for you to buy or lend a small unit for a while, a capacity of 02-0.5 cubic meters. m.

Video - homemade concrete mixer

Before preparing the mixture 5-6 hours before the slag moisturize. This will allow you to better bind the grains of cement and the filler fraction. It should be noted if you fill out wooden or metal forms without the possibility of sending vibro-mask, the mixture should be liquid.

Pros and cons of the use of slag blocks

The advantages of the slag block include:

• possibility of manufacturing in the country area or in a private house;
• the drying of the material can be held both in the autoclave (industrial production) and outdoors (with independent manufacture);
• the building from the slag blocks carries the minimum heat loss;
• material inexpensive;
• the construction of the construction is carried out quickly, given the large size of the blocks;
• when kneading the solution, you can, changing the proportions, to give him certain qualities;
• it is subject to a slag block of any sizes.

Shlakoblock flaws:

• low speeds of frost resistance, but using special additives can be enhanced;
• there are doubts in terms of environmental friendliness, especially for products made on the basis of a domain slag;
• as for the characteristics of the absorption of the liquid, the material has strong moisture absorption requires special protective coatings;
• fragility (for the construction of height, this material is clearly not suitable).

1. The highest strength is the blocks made with the addition of cement. The next place is occupied by blocks from lime.
2. If the minor granules are replaced by part of the sifted sand, then the strength of the products will increase slightly.
3. The compound of cement and lime (either clay) in the 3: 1 proportion will save that it will absolutely not be charging on quality.
4. Before you begin to pour the solution, the form should be cleaned and wipe. This will eliminate the adhesion of the obtained blocks to the bottom and walls. For such wiring, diesel oil, exhaust oil or similar means are used.
5. The density of the solution is a direct fascination rate. What he is thick, the faster the block will be able to frozen. The main characteristics of the quality of slag blocks depend not only on production technology, but also from the choice of solution. Below are given different types Mixtures, the use of which demonstrates certain characteristics that are presented to the material.

One of the most common materials for the construction of bearing walls and partitions of residential buildings, as well as small production buildings are concrete blocks. Their popularity is due to low cost, excellent performance and large quantity varieties, which allows you to choose the desired block for almost any tasks.

The instruction given in this article will allow you to learn how to make concrete blocks yourself, and also acquaint with the existing views.

Blocks made of concrete for walls

Varieties of artificial concrete stones

Consider the main species + the characteristics of the construction concrete blocks that are most common in modern construction.

Slagoblock

These wall stones are manufactured using the vibropressive method. concrete solution on special platforms.

The composition of the mixture from which the slag roll is manufactured, may include:

• crushed stone for concrete products;
• brick fight;
• sawdust;
• ceramzit.

Specifications Concrete blocks with slag leave much to be desired, but due to the fact that their price is one of the lowest on the market, the slag block is widely used in private construction.

But the cost is hardly the only advantage, since they are far behind the other materials in the following parameters:

• durability;
• heat-saving parameters;
• strength.

The main scope of the application of blocks is small buildings that will not be exposed to a large load:

• shed;
• garages;
• summer kitchens;
• workshops and so on.

Less common material, which is manufactured from the following components:

• organic matter (mainly wood);
• binder element (powder);
• hardener.

In fact, this artificial stone consists of sawdust enclosed in a concrete shell.

The benefits of the material are obvious:

• low weight of the concrete block;
• high thermal insulation properties;
• good sound insulation;
• effective air exchange.

To protect the blocks from negative impact ambientStones are treated with a special solution. This prevents the formation of mold and prevents rotting.

Arbolit is perfect for the construction of small houses that are suitable for year-round residence without the use of additional thermal insulation.

Arbolite block

Gasoblocks and foam blocks

Capboral concrete blocks according to GOST, determining their technical characteristics, 70-85% should consist of artificially created pores (cells) filled with air. The most common foam and gas blocks.

These materials have the following advantages:

• have a low weight, with the result that the transport of concrete blocks and their installation in private construction does not require the use of special equipment;
• easily processed - it is possible to give the necessary shape to the cellular unit using an ordinary hacksaw for wood;
• walls from cellular concrete blocks are well kept warm and have excellent soundproof properties.

Concrete blocks with a cellular structure are made of a solution, which includes sand, cement and aggregate. To form a foam, lime, aluminum powder or other foaming agent is added to it.

Note!
Unlike foam concrete, aerated concrete is subjected to additional processing in an autoclave furnace, where it affects high temperatures under high pressure (10-12 MPa).
As a result, this material acquires increased strength: to expose or break it almost impossible.

Block from cellular concrete

Independent manufacture of blocks

Production technology artificial stone of cement mortar With the filler relatively simple, which allows you to make blocks from concrete yourself.

Preparatory work

At the initial stage, the dimensions of the future block should be determined. When independent manufacture The parameters of each individual element are taken on the basis of the desired wall width.

The thickness of the bottom of the block should not be less than 2 cm, and the walls of emptiness are at least 4 cm. In this case, the standard stone with dimensions of 20x20x40 cm with voids inside weighs about 40 kg, which makes it comfortable for masonry walls.

For the manufacture, you will need any flat platform, set by polyethylene film and special forms without bottom.

Material for forms will serve:

• boards;
• plywood.

To protect the tree from damage, the inside of the shape is coated with sheet metal. In the same way, the liners are made, thanks to which emptiness is formed in the finished block. They improve the thermal insulating properties of the material and make it easier.

Molds for the manufacture of concrete blocks

Concrete blocks with their own hands can be faster if you make several forms at once in one block. This requires a plywood or a width board equal to the height of the future block. The material is cut into parts and fastens with the help of self-tapping screws. Next, the inner partitions are made.

Tip!
To the frozen block easily separated from the form, all of its parts need to be lubricated with kerosene, machinery or toxol.

Manufacturing process

For casting blocks from a concrete mixture, the following materials will be needed:

• gravel with shallow fraction;
• cement;
• sand;
• water;
• lime;
• wire for reinforcement.

The amount of each of the components is determined on the basis of your artificial stone needs. The proportions of cement, sand and gravel are taken in the ratio of 1: 3: 5.

For the kneading mortar, it is better to use concrete mixer

The entire subsequent process is divided into several stages for convenience.

In the concrete mixer should be placed gravel, sand and cement. Then, in the process of mixing with small portions, add lime. In the last stage, water is added. The finished solution should not be too liquid in order not to flow out of the form. As a result, you will get the M135 brand concrete with fine gravel aggregate.

The mixture of concrete mixer is laid in a layer for 2 cm thick. After that, the liners are fixed, which are necessary for the formation of emptiness inside the artificial stone. You can fix inserts using transverse speakers that are removed after filling in the concrete of one third of the form.

The bottom of the form is appropriate to be displayed with newspapers or paper.. This will prevent concrete setting with the base. The mixture is filled with the form, should be semi-dry. This is checked: taking a little solution, it should be minimized and put on a flat surface. A lump must keep the shape, not spread.

After filling out the form until half the height, the reinforcement should be laid, which will make the future stone more durable.

Instead of inserts to form voids inside the concrete block, you can use empty bottles. It closes with a plug and inspired inside the stone.

After the final filling of the form, the solution must be tamped and aligned with the help of a trowel.

You can remove blocks from forms on 4-5 days, but you can use them in work only after 2-3 weeks, as soon as the solution fully solids.

Self-made block made of concrete

The technology described above allows without applying special effortsMake concrete blocks with your own hands. The technical characteristics of the finished products are practically nothing to yield to the analogues that are sold in building supermarkets, and the size is perfect to fit your requests. In addition, it is possible to significantly reduce the cost of buying building materials and their delivery.

More details are familiar with the material will help the video in this article.

For the manufacture of concrete blocks as a filler fit: slag, ash, coal burning waste, sewing rubble (stone, granite), brick waste, gravel, sand, sawdust (after processing), ceramzit, perlite, sand and gravel, Grasslak, hall, crushed stone, sawdust, plaster, brick fight, etc.

Machine for the manufacture of slag blocks

Slag block solution: coal slag: large sand (clay): gravel 5-15 mm, cement M500, water (7: 2: 2: 1.5: 1.5-3). It is important to strive behind the amount of water so that the blocks do not spread when removing. The solution should crumble when falling on the ground, but in the fist should be connected.

For the plasticity of the blocks, you can add a plasticizer (5 grams per unit - strength, waterproof and frost resistance, less cracks) when vibrating, it is possible when vibratingressing, but you need to add too much for the effect, and this is expensive.

So that the slag blocks were durable, you need to consider:

Sand quality - need large.

Slag is perfect domain.

Cement - high-quality M400.

Equipment - to better press, you need to achieve vibropressing.

Cooking time and storage of concrete blocks

mother with ribbon can be in a day. Full drying in a couple of months. In day, blocks can already be worn - do not break, put in a week.

When using a plasticizer, ready-made blocks can be removed from the site and stored after 6-8 hours. Without UPD - in two days. Keep ready-made slag concrete blocks in pyramidal stacks of 100 pieces with a small (2-3 cm) gap between the blocks - in order for the "sidewalks".

At first, the concrete can be prepared manually. Subsequently, more efficiently and easier - on an electric concrete mixer with a volume of 0.2-0.5 cubic meters. m.

The production site is a room with a smooth floor, good ventilation / heating or a flat site on the street under a canopy.

The advantages of slagoblok

• low cost
• high speed construction from slag blocks;
• good sound insulation
• good thermal insulation
• can be made for yourself and for sale

Negative opinions on the manufacture of concrete blocks do it yourself

The machine is beneficial only if there are cheap or "free" raw materials or with huge amounts of work.

Empty block made anywhere, more expensive, section of the wall of the same size made by the removable method or failure formworkMoreover, you spend your time and strength. Therefore, mainly the sale of these machines is just the opportunity to make money on others.

Example of expenses and cost of manufacture of homemade blocks

0.011 cubic meters of solution takes place on the production of one slag block, in proportion 1: 7 (cement: Granchlak), i.e. 1 cement bag \u003d 36 blocks.

Legislation

Decisions of the Government of the Russian Federation of August 13, 1997 No. 1013, State Standard of the Russian Federation No. 86 dated 08.10.2001 and the Gosstroita of the Russian Federation No. 128 dated December 24, 2001. The list of products requiring mandatory certification does not include building concrete blocks with various fillers (slag, clayzit , Opid, etc.), as well as vibration-forming equipment for their production.

Production of shape with your own hands for casting concrete blocks

The shape for independent manufacture of slag concrete blocks is a 3-mm metal box without a bottom with handles. In order for the facial part of the blocks to be smoother, they need to be dried on a rubber tape, moistened with a solution of some detergent.

We begin the manufacturing process

What is needed for that? First of all, you need to decide on the size. I propose to stay in the following sizes: 200x200x400 mm and 200x200x200 mm (these are "halves" and they will necessarily need during work).

Now prepare formwork formwork. To do this, it is necessary to cut the old furniture shields from the chipboard of the corresponding dimensions and connect screws through the transverse and longitudinal partitions, dried from a 40 mm board (see Figure).

This form is convenient because it is possible to simultaneously lay 4 blocks. Next, the form without the bottom is set to an even base under a canopy, covered with polyethylene film. Their inner surfaces are scattered by an alcoholic machine oil. This is done in order to make it easier to produce blocks after they harden.

Now prepare the material from which we will make blocks. In the concrete mixer, and in the absence of it in any container, pour gravel sand and some lime. After it is mixed add cement.

The ratio of the bookmark must correspond to the proportion - 1 part of the cement on 4 parts of the aggregate. All this is thoroughly mixed and diluted with water to the desired consistency. The solution should turn out to be conveniently layered in the form.

Further, two shovels of a solution reinforcing the wire are stacked in the form. On all, it should be placed "Walt" two glass bottlesplugged by traffic jams. Bottles will play the role of sealed glass blocks and thanks to them inside the block two air chambers are created, creating thermal insulation.

After laying bottles, the layer of the reinforcing wire is poured again. From above, everything is covered with an additional layer of solution, which is loaded with a trowel. When pouring the solution, it is necessary to tamper it well that emptiness would not be formed inside the form. When concrete hardens, the side wall shape is removed and the blocks are removed.

Making blocks better in cloudy weather, because the time of evaporation of water from the solution increases, which reduces the likelihood of cracks on finished blocks. If you still work in hot time, then cheat should be placed in the shade and desirable to cover them in order to reduce the rate of water evaporation. Using this method you save up to 60 percent of funds.

That's probably all I wanted to tell about people's Fashion Making concrete blocks with their own hands at home.

The modern building materials market offers a large range of wall blocks. But not everyone knows that it is quite realistic to reduce the construction of a private house, cottage, garage or utility room. It is enough instead of buying a brick or slagoblock yourself to make their manufacture. To do this, you need to use the machine for the production of blocks, and if it does not allow the budget to make a vibropressing machine yourself.

Inexpensive factory models of vibrationans do not differ in high performance, but it is not necessary for private use. True, buy a machine, for the construction of a small house where about a thousand blocks will need. standard size- It will not be quite profitable. Therefore, as an option, you can consider rental equipment for a certain period. This will be enough for the workpiece of building materials.

Factory machine for making building blocks with their own hands

Varieties of building blocks

The brick remains the main material in the construction of high blood, but for low-rise construction is cheaper to use other building materials. If we exclude the wood, which is now expensive, the choice will still be diverse. Modern wall materials Produce from:

• foam concrete;
• slag concrete;
• aerated concrete;
• ceramzito concrete.

Block Characteristics Table

As a filler of slag blocks, the most different and sometimes exotic materials that are waste generations are used: explorer, glass and brick battle, sawdust, wood chip.

Consider for a start, how the ceramzitoblocks and slag blocks are made independently, as the most budgetary among all the above building materials.

Expert opinion: Machine for the production of slag blocks

If you do not possess the necessary knowledge and skills for self-making machine, we advise rent equipment. If you wish for self-making machine for the production of building blocks, use only high-quality materials. Soviet much attention Perform the stage of creating a drawing of the structure and calculate all the nuances in advance. For the sample take the factory equipment or the finished equipment of friends and acquaintances.

Keramzitoblocks do it yourself

If there are no problems in your region with a clayzit, you can assume that you are lucky: a ceramzitobeton, despite the cheapness, occurs on sale rarely, but this building material is characterized by a variety of positive properties. For the manufacture of ceramzitoblocks, it will be necessary:

• actually clamzit;
• cement;
• sand;
• water.

The main material for creating a mixture will be a grainzit of small fraction

When mixing the solution, it is important to adhere to a specific sequence: the water is added to the water, then cement, in the end - sand. The proportions of the solution are as follows: nine liters of water use 54 kg of clay, 9 kg of cement and 27 kg of sand. It turns out the mixture weighing about 100 kilograms, with the output of finished blocks in the amount of 9-10 pieces.

Technology manufacturing ceramzite concrete blocks

If it is not possible to use a specialized machine (such equipment is expensive), the ceramzite concrete can be carried out in non-industrial scales using special matrices. The corresponding container for the solution, a flat platform and formwork, made of wood or metal in the form of the letter "E", will also be required.

Reduce temporary losses and reduce labor costs will allow concrete mixer - standard equipment in the arsenal of the builder. With a shortage of time, the problem is solved by using a vibrostank, a simple model of such a machine can be made independently.

To do this, it is enough to form a low-power, but high-breeding electric motor, turning with the help of eccentric in a full-fledged vibrator. The oscillations of the matrix force the mixture to be distributed in the form as tight and evenly as possible, improving the strength characteristics of finished products. The maximum performance has vibropresses made in factory conditions: professional machines are equipped with additional equipmentallowing to automate the process by excluding heavy manual work. But there are such vibropressive machines a lot.

Production of slag blocks with their own hands

Keramzit is a wonderful and inexpensive material for the manufacture of building blocks, but even more economically Construction management is the use of slag blocks. With comparable characteristics on sound and thermal insulation, the slag concrete is made of materials, the cost of which is an order of magnitude lower.

Industry is not interested in making slag-block building material - it is cost-effective to produce expensive analogs (building blocks of foam concrete, aerated concrete, bricks). But the special equipment for the formation of blocks from the slag concrete is on sale, and a lot. The variation of prices for such vibrationans is huge: from simple models with static matrix, which can be collected and in garage conditions from girlfriend, to fully automated lines.

Shlakoblock: manufacturing technology

The modern slagoblock has dimensions of 188x190x390 mm, a complete building material is characterized by sufficient strength to arrange foundations and multi-storey construction, hollows are used in all other cases. The voids can be a round, rectangular or square shape, the amount varies from one to 8-10 emptiness, the index of emptiness lies in the range of 25-50%. Virtually no inferior on the strength indicators of monolithic products, hollow slag blocks allow you to save expensive cement almost twice.

Filler in production can be:

• coal slag;
• small-phrase gravel;
• opening rubble;
• sand;
• brick waste;
• glass fight;
• ash;
• perlite;
• gypsum;
• sawdust;
• wood chips.

When mixing the solution, the proportion will depend on the composition of the filler. The main condition is that the finished solution is not spread. Cement in the production of slag concrete is not below the M400 brand, to improve the operational properties of the finished product, plasticizers can be added to the solution.

Portable machine for making slag blocks with their own hands

The factory recipe can be a factory formulation with a landmark with independent production of a solution for slag blocks: for seven parts of the domain slag - two parts of coarse sand, one and a half of the cement and up to three parts of water. The method of checking the consistency of the consistency of the solution with the requirements is simple: throwing a handful to the ground, it should crumble. If you collect a solution and squeeze it in a fist, it must take the shape of the ball.

Focus on standard dimensions are not necessary: \u200b\u200bthe manufacture of blocks with their own hands is an individual process, and many prefer to establish production using multiple form sizes (for example, 200x200x400 mm), which simplifies the conjugation with other structural elements of buildings under construction.

Cooking slag blocks without special equipment

If there is free time and the absence of the possibility of manufacture the simplest vibrostanok for the production of slag concrete, it is advisable to use the shape, as the walls and the bottom of which boards or sheet metal are used. It is preferable to use one matrix for the manufacture of several blocks of slag concrete, at least in order to save materials. For the formation of voids in the form for filling the solution, you can use bottles, trimming metal pipesWooden cylinders or bars.

Manual machine, for the manufacture of slag blocks and ceramzitoblocks at home

The procedure itself is simple: we prepare the solution, pour the slag concrete into the forms, grow up, removing the excess. A day later, blocks can be carefully obtained, laying out for drying on a horizontal surface. To protect against cracking and wetting of the finished material during drying, cover the stack from the slag concrete with a polyethylene film.

You can use homemade slag blocks a month after their manufacture. This moment should be taken into account and make the manufacture of building materials in advance.

Adding to the above-described production scheme, slag concrete, vibrator, provides the ability to significantly improve the quality of products and at the same time accelerate the process.

Collect such a machine is easy, subject to all recommendations, this equipment will not work worse than the factory analogues. The simplest option The vibropressive machine involves the use of a self-made matrix, a vibrator and a manual press. To reduce physical exertion, manual press can be improved by using the lever system.

Drawing homemade machine With vibromotor for the manufacture of slag block and ceramzitoblocks

A set of tools and materials required for the manufacture of a vibrostank with a metal form:

• welding machine;
• bulgarian,
• a set of keys;
• vice;
• sheet metal with a thickness of at least 3 mm;
• pipes for creating voids with a diameter of 8-10 mm;
• schawler, Metal strips;
• low-power electric motor (up to 1 kW);
• connecting elements (bolts, nuts, plintes).

The main element of the machine for the manufacture of blocks with their own hands is the matrix, the dimensions and the shape of which are chosen on the basis of the production necessity.

Sequence of actions in the manufacture of self-made vibrostanka:

• The grinding of the sheet material is cutting out the wall of the matrix. If the form is intended for the manufacture of several block products - we provide for the presence in the matrix of the appropriate number of partitions.
• Cut from the pipe the required number of boobs (at the rate of 3 pieces on the brick), the height of which should be a smaller height of the matrix by 3-5 mm. The tape of pipes is achieved by using the following method: cutting the pipe up to half and crimp the blank in the vice (for thick-walled pipes, a lathe can be activated).

Drawing for the manufacture of a machine with a lightweight extrusion of building blocks

• Each segment of the pipe is brewed tightly on both sides.
• We weld to the pipes of the plate, connecting each other. For mounting to walls, it is better to provide a removable connection, which will allow you to remove the limiters for the production of monolithic slag blocks.
• Using welding, fix on the long outer wall bolts for fastening the electric motor.
• From above, we weld the metal apron.
• We make a press in the form of a thick-walled plate, we provide for the presence of holes with a diameter, slightly exceeding the smaller diameter of the pipe stoppers (so that the press enter the matrix to the distance of no more than 50 mm).
• We weld to the press handle.
• Install the motor. An eccentric is welded to the motor shaft (ordinary bolts are suitable as the material for the eccentric, which are welded parallel to the shaft and leave the place for winding the nuts, which will allow the fluctua amplitude to adjust).
• Thoroughly clean the device, water surface, stain a homemade unit for blocks.

Making slagoblocks

Preparation of the solution is desirable to produce using concrete mixer: the presence of large-scale fillers makes it difficult to obtain a high-quality mixture manually. Before the fill of the slag concrete in the matrix of the wall surface, it is necessary to lubricate with machinery or similar product. This prevents the adhesion of the solution to the walls of the matrix.

Depending on the desired result, the form for the manufacture of the block will differ. The construction market is full of foreign / domestic manufacturers of blocks for concrete. They produce material of any category of complexity. When independent repair, the option of creating a block from at home is quite real.

Please note: the installation of blocks will take much less time, relatively with other materials, due to its size.

Scope of application

More often, concrete blocks are used as a base element of buildings: garages, high-rise residential buildings, offices, private houses, country sites etc. The scope of application is not limited to large-scale construction projects. Perhaps self-making / use of concrete blocks at home. The only difficulty: it is necessary to use additional construction techniques (dryer, concrete mixer). As a dryer, you can use a closed room (utility), with the presence of a carrier. The required temperature for the dryer with your own hands is 70 degrees.Concrete forms are used for the following products:

• construction concrete material;
• decorative architectural elements (vases,);
• paving tile (type can vary);
• fences (including decorative nature);
• reinforced concrete construction plates.

Feature: Depending on the product we need, quality, details, the form casting will vary. To create a form, and then the product should be accurate calculations, carefully monitor the process, follow the rules of creation, know the features of the material / future product.

Material for manufacture

A variety of concrete blocks, the features of their use, put forward a set of new materials to the market. The source material that will give the form quality characteristics may vary depending on the requirements for the final product. Each material is calculated for a price category, quality, processing methods, technical indicators.

Silicone forms for bulk products.

Production of products with small parts, the creation of the most accurate copies requires the use of elastomeric forms. Application area:

• complex bulk products;
• high-precision bas-reliefs;
• architectural construction.

Production data production is impossible without the following components:

• rubber (synthetic rubber);
• formoplast;
• compounds (polyurethane / silicone).

Approximate material consumption: 10-40 kg / m2.

Disadvantage: make such a product at home is extremely difficult. The specialized technique of cooking, crushing destination should be used. In addition, before proceeding to work on the substance, you should consult a specialist. Due to the subtleties of working with the material, such a consultation is mandatory.

Plastic

Large-sized erections that do not require accurate geometric calculations, it is better to produce from plastic forms. Main materials:

• fiberglass (low compatibility with cement matrix, due to which cracks, faults are possible);
• hard plastic (prone to warmers, so the main scope of application is paving slabs, borders, concrete paving);
• aBS leaf plastic (prone to resolveing, an additional silicone lubricant should be used. From it you can make a small material);
• sheet / film polystyrene (well transfers the texture, outlines of objects, is a fragile material);
• pVC plastic (the most durable, high-quality. The maximum low adhesion does not require cleaning and lubrication).

If you decide to use plastic to make a block, be sure to follow the presence of a rigid formwork. It is the formwork that will give the material the desired relief, rigidity, will provide easy extraction. In case of non-compliance with this rule, the product is either collapsed during drying, or the result will be poor-quality, short-lived.

Independent creation of form

Please note that the final processing of the product should be carried out after full of frozen. If the product is raw, next steps (for example, cutting) illogical, ineffective. Creating a form:

• Start production from the submitted means. For example, you can use foamflast. Cut the stamp, fill it with a pre-prepared mixture (sand cement). You will receive one instance of the form for concrete scenery. You can use plastic containers of different sizes instead of stamps.
• Collect the product from cropping chipboard, wood. The main rule - the surface must be smooth. In the case of roughness, cracks or concrete are formed between blocks and the surface, it will be uneven distributed, which makes it difficult to extract the product.
• Fill the concrete mixture, leave it a few days before complete drying (depends on the type of mixture, the material of the product. The desired indicators are viewed in the instructions for the material).
• After complete drying, it is neatly reach (for example, a spatula or a similar object), a finished product.
• Swipe (if necessary) required decorative work.

If you do not have time / desire to spend the process yourself, use the services of construction companies. By contacting the company you need, you can place the order on the form you need. Explain the purpose of the construction, the desired material, mark the timeline. For the priced price (according to personally, by phone) you will be advised and accept an order. Thus, you can be sure of the quality of the product, its durability, the correctness of the creation.
