Scope of use, types and advantages of home foam concrete

The popularity of foam concrete in the construction industry is explained by its advantages:

1. Economic expediency.

The production process does not require special material investments, the material is made from available materials, and the possibility of home production significantly reduces its cost.

2. The vapor permeability of foam concrete.

Due to the fact that the material passes the air, a favorable and healthy atmosphere is created in the room, mold and fungus are not formed.

3. Environmental safety.

Foam concrete is environmentally friendly material, since in the production process, toxic substances are not added to it. The main components are sand, water and cement. Some manufacturers improve the performance of the material by adding plasticizers and hardeners.

4. The material has lightweight.

This advantage greatly simplifies the process of transporting and laying foam concrete. In addition, a massive foundation is not needed for such a house, and construction work is carried out even in seismic areas.

5. The speed of installation.

The use of foam concrete as a building material for the construction of walls allows you to build a house in 2-3 months.

6. High heat and soundproofing indicators.

The manufacture of walls from foam concrete reduces the total cost of the building, as the costs of acquiring heat and soundproofing materials are reduced.

7. High fire safety level.

Foam concrete does not burn and does not support combustion, in addition, it prevents the spread of flame.

8. Universality of further finish.

The walls of foam concrete are putty, plastered, sheathed with wood, lining or siding. There are no restrictions in this regard.

Among the disadvantages of the material, we note a high porosity, which on the one hand improves thermal insulation indicators, and on the other, it reduces strength. Therefore, the transportation of foam concrete is carried out with particular caution. The walls of foam blocks are mandatory reinforced, in order to avoid the appearance of cracks on their surface after shrinkage. In addition, foamed walls need decoration. The lack of external decoration leads to the absorption of carbon dioxide with material and a decrease in its strength. High -quality exterior decoration quickly solves this drawback. The best option is to use brick as a finishing layer.

The scope of use of foam blocks is not limited to the construction industry. The material is used for the construction of walls, supporting structures in country houses, residential and office buildings. In addition, foam blocks are widely used in the process of insulation of the already erected walls, improved sound insulation, in the construction of interior partitions. With the help of this material, old buildings are reconstructed and repaired, their number of storeys is increased and the sound insulation of the ceilings is improved.

Foam blocks differ in density and in the amount of pores in the material. To designate this indicator, the letter D. The recipe for the production of material directly determines its quality and brand, and these indicators are the main ones in the field of use of foam blocks. In relation to the place of application, the material is divided into:

• foam blocks from which the internal partitions D100-300 are erected;
• thermal insulation material D400-500;
• constructive and-insulating D600-900;
• Structural foam blocks D1000-1600.

Foam blocks of the highest density are characterized by the lowest heat -insulating indicators and are used to reinforce the ceilings and work of constructive purposes. Their cost is much higher than that of foam blocks of the D100-300 brand.

Keep in mind that air humidity in the process of laying the material should not exceed 60%. Otherwise, a vapor barrier film is applied to the inner surface of the material. For laying the material, both a regular cement -based solution and special glue are used. The use of adhesive composition has great advantages, since in this case, cold bridges are not formed inside the walls. In addition, the number of adhesive composition for fixing foam blocks is much less than cement.

Do -it -yourself foam blocks

The standard two -stage technology for manufacturing foam blocks involves the use of equipment in the form:

• foam generator and compressor installation supplying air;
• the mixer, at home, is replaced by a concrete mixer;
• forms for filling the solution and solving it;
• additional devices in the form of a pressure gauge and pumping equipment.

Before starting work, prepare the drawings of equipment for the production of foam concrete. Next, get the module - the most costly component. This part of the device converts the foaming agent into a foamy substance, supplying it to the solution.

The supply module serves as a place for filling the solution that forms foam. Any tank, suitable size, will cope with this function. The transformation module - processes the solution, making foam from it. Dosing equipment - supplies foam in a certain density and quantity, determines the brand of the resulting material.

Among the main parts of the foam generator, we note the elements in the form:

• nozzles;
• joining flange;
• suction pipe;
• corps part;
• shift chambers;
• diffuser.

For the independent manufacture of this device, prepare two pipes, pump, hose, valve. In addition, stock up on welding machine and drawings, according to which further work is carried out.

The factory pipe for the foaming agent is distinguished by a peculiar structure, one part of it has a narrow structure, gradually expanding. Thus, the speed of passing the fluid through the pipe increases, at the output, increasing as much as possible.

Next, make a foam and camera for a turbulent component connection. To do this, weld the pipes in the amount of two pieces to one pipe. One of them is located in the end part, and the second - feeding foam, with a corner. Make sure that the pipes are located at right angles with respect to the tube.

On each of the pipes, install two valves each:

• shut -off type - with it, the supply of the foam is stopped with it;
• Adjusting type - regulates the speed and number of foam supplied.

Adjusting valves are needed only for primary setup, in the future they are not used. Recommendation: The lateral pipe in diameter should be twenty percent more than the end.

The next stage is work on the foam. The second preparation of the pipe is equipped with a nozzle, which provides the output of the finished composition. A funnel is installed on the output pipe, which reduces the speed of the foam concrete mixture. Set the filter inside the workpiece, which converts the emulsion into foam. It is possible to purchase a finished filter or its independent manufacture from an ordinary brush for washing dishes.

Keep in mind that in this case, use a wire type mesh, not a spiral. Remember them along the entire length of the tube, in order to avoid the loss of the ruff, additionally strengthen it with a puck.

Next, the mixing chamber is connected to the foam card. At the same time, the installed pipes are located at opposite ends. To improve the speed of transportation of the composition along the pipe, install an element between them in the form of a nozzle or a jack of nozzle. Keep in mind that the second option, although cheaper, is worse, as it reduces the efficiency of the device by 30%.

Connect the compressor installation with the end pipe and the connection chamber. Keep in mind that the compressor power should be at least 5 atm, in addition, it should have a receiver, manometer and a reduction valve.

Install the container on the floor, connect the hose to it to supply foam to the mixer. Combine the resulting installation with a pump that will simplify the supply of foam. This device is not inferior in the power of the purchased installation, but its cost is 3-4 times lower.

The next stage is the construction of forms for foam blocks. For these purposes, various materials such as wood, plywood, steel, polymers are suitable. The main requirement is the creation of a strong and even surface that is not prone to deformation. To make the form, follow the stages:

• Calculate the size;
• Create a drawing.

Standard foam blocks in length, width, height in a proportional plan are 4-2-1. Adhering to such a ratio, it turns out a material suitable for the construction of walls and convenient dressing, without cutting blocks. That is, at a depth of a form of 15 cm, in width and height it will be 30 and 60 cm.

In the individual production of foam blocks, there are enough thirty forms for foam block. Mount the partitions so that the largest part of them is located on top. Thus, foam blocks dry faster and evenly gain strength. The option of making multi -level forms is possible.

First, build the bottom of the shape, hardly fix the walls on it and install the removable partitions inside. We recommend that you dwell on the collapsible version of the form, thus, the size of the foam block changes, if necessary. In the manufacture of a plywood mold, connect the parts between themselves with nails and choose its laminated options. Homemade forms allow you to make foam blocks of the required size and shape. Keep in mind that before pouring foam concrete in forms, wooden products are pre -covered with a film, otherwise, wood will absorb moisture from the solution and deform the characteristics of the resulting product.

Step -by -step instructions for the manufacture of foam concrete

For the manufacture of foam blocks, special equipment and mixture will be required. The composition of the solution for foam concrete includes the ingredients in the form:

• 310 kg of high -quality cement;
• half a ton of fine sand;
• 210 liters of water;
• 1-2% of the foaming agent in the ratio with a mass of cement;
• modifying additives.

For the manufacture of a foaming agent at home, mix the components in the form:

• 150 grams of caustic soda;
• 1 kilogram of rosin;
• 60 grams of carpentry glue.

The foaming agent is not necessary to make at home, a variant of finished compositions is possible. The instructions for the foamer for foam blocks indicate the proportion of adding for the material of a particular brand.

For self -manufacture of the foaming agent, follow the instructions:

1. Prepare the adhesive solution. Pour glue with water in a ratio of one to ten, leave for a day. Next, heat the tank with the composition to a temperature of sixty degrees, constantly stirring, the mass should become homogeneous.

2. Caniphol soap is prepared in this way: bring the soda to a boil, add rosin, boil the composition for 120 minutes until uniform. Caniphol is pre -chopped.

When cooling soaps up to sixty degrees, connect the compositions to each other in a proportion of one to six.

Pour the composition into a foaming unit to obtain high -dense foam. The optimal value of foaming is eighty grams per cubic meter. With a lower indicator, the quality of the finished material and its thermal insulation characteristics worsen.

The quality of the foam is determined in this way, fill the bucket with the composition of the bucket, turn it over. If the foam is held tightly and does not flow, then the proportions are correct.

The foam block manufacturing scheme looks like this:

• supply of sand with cement;
• adding water;
• getting the composition into the porizator;
• Penton's submission to forms.

Keep in mind that quite often the first 3-5 foam blocks are not obtained the desired quality. This is due to the following reasons:

• the difficulty of adding components in the desired dosage;
• decrease, increasing water level;
• a large number of foaming educational;
• the wrong time of kneading;
• determination of time for a set of strength;
• Selecting the drying mode of the material.

Experimenting, all these indicators lead to normal. Further recipe for the production of material is constantly used. Defective foam blocks are used to fill the floor.

The lighter in the production of foam blocks of the D900 and higher brand, since they contain a small amount of pores, however, they have less heat -insulating properties.
