Production of foam concrete at home for
Individual construction is advisable in the case of a large amount of work.
Then the cost of buying equipment is completely paying off. But, there is a way yet
More cheapening manufacturing process - make equipment for production
Foam blocks do it yourself.
Consider the specified options consistently in the form of
Step by step instructions for beginners without experience in construction.
1 option - mini foam concrete production with their own hands with
using finished equipmentFor the production of foam blocks at home
Installation is purchased - specialized equipment complex (machine), and
Foam concrete mixture is prepared independently.
The composition of the foam mixture:
- Cement (Portland cement, M-400 brand and higher. Cement should
be necessarily fresh) - 310 kg;
- Sand (fine-sided or crushed, sacred sand) -
500 kg;
- water - 210 l;
- The foaming composition is 1-2% of the mass of cement;
- Modifying additives.
Separately, focus on the foaming agent. Can be used
Ready composition, for example, PB luxury (90 rubles / kg) or Foamcem (150 rubles / kg) or
Make it yourself.
Foaming agent for foam concrete
The composition of the foaming agent:
- caustic soda (caustic soda) - 0.15 kg;
- rosin - 1 kg;
- Joiner glue - 0.06 kg.
a lot of time. Therefore, it is appropriate only with significant amounts of work.
How to make a foaming agent for foam concrete at home
Preparation involves performing two stages:
- Mixing the adhesive solution. For this slices of dry glue
Fill with water (1:10) and leave for a day. During this time glue a bit
Wake up, but will keep shape. Therefore, water tank and glue heated
up to 60 ° C (with constant stirring). Glue solution is ready when all
The pieces were dissolved and formed a homogeneous mass;
- Preparation of rosin soap. For this purpose, Natra brought
to boil. Then the rosin is gradually introduced into it. The boiling process will occupy
About 2 hours before the complete dissolution of the rosin.
Note. Rosin should be crushed.
Both compositions are mixed when the rosin soap cools up to 60 ° C.
Note. When mixing, the rosin soap is poured into
glue solution. Proportion for mixing 1: 6.

The resulting mixture is poured into the foam generator and receive foam
High density. Optimal for use is considered foam density 80
GR / DMKUB. Use less dense (more air foam) worsen quality
Block and will lead to its rapid destruction.
Note. Check the quality of the foam, you can fill it
bucket. After turning the bucket, the foam should be kept inside.
The foam block production scheme is shown in the figure.

Note that like the first pancake, the first foam concrete
Blocks usually also come out. There are several reasons for this:
- the complexity of dosing components in the solution;
- increased / reduced water content in solution;
- Increased content of the foaming agent in solution. His
Consumption should not exceed 1.5 liters. per 1 m / cubic meter.
First, because the foaming agent is expensive.
Secondly, because the increase in its mixture
Increases the time to harden concrete.
Thirdly, because it will reduce the strength of the block.
- varying time kneading;
- Experimental time definition for durability
blocks;
- The mode of drying ready (fastened) blocks.
Unfortunately, such experiments not only prolong
Construction time, but lead to additional costs. However, as
Testify users, they are fully justified. Especially since defective
Foam blocks can be used as a backfill under the floor, and used
Equipment for the production of foam concrete can be sold.
Note. As practice shows, it is better to do
structural foam blocks (brands D-900 and higher). They contain less pores
Compared to thermal insulation, and beginners to make them easier.
2 option - manufacture of equipment for foam concrete with their own hands
To begin with, we note what equipment needs for
Production of foam blocks when using classic two-stage technology
production.
The factory setting of a mini-plant for the production of foam concrete includes:
- foam generator with air supply compressor;
- Mixer (private production uses usual
concrete mixer);
- Forms for foam blocks;
- Additional equipment: pressure gauge, pump.
Equipment of standard foam concrete installation is shown on

How to make a foam generator for foam concrete?
To do this, make a turbulent mixing chamber and
Basic Ponocentron.
Making a mixing chamber
To one of the harvested pipes to weld two nozzles. MoreoverOne of them (by which air will be served) it is advisable to place with
end. And the second, designed to feed the foaming emulsion to welcome
on the side (at an angle of 90 °).
Both inlet nozzles (end and side) are equipped with two
Valves:
- locking (allowing to overlap the feed of the foaming agent);
- adjusting (allowing you to adjust the feed parameters,
Change pressure, pressure, quantity, etc.).
In practice, after the feed parameters are adjusted
Mixtures, adjusting valves do not use.
Note. The diameter of the side nozzle must be 15-20%
More diameter of the end nozzle.
Production of Ponopathron
The pipe is welded to the second workpiece. It
Designed to exit the finished mixture. Output nozzle expedient
Equipment to a fixture in the form of a funnel to reduce the speed of the mixture.
Filter is placed in the workpiece. The purpose of which, the transformation of the emulsion in
foam. You can purchase a finished filter.
But its function with no less success can perform
Metal meshes (rods) for cleaning dishes.
At the same time, the spirals are not suitable, only wire. These
The mesh should be tamped as close as possible along the entire length of the polypathron pipe.
So that the grid particles do not fly together with the mixture to output the pipe
Installed "ERS", inside which the mesh washer is installed.

Next, you need to connect the mixing chamber and a pennipotron.
Naturally, it is necessary to make it so that the welded nozzles are placed with
opposite ends. To ensure an increase in the speed of passage
foam concrete mixture on the tube, you need to install the nozzle of the boiler between them or
Washer boiler. Replacing the nozzle on the joyaker will reduce the design efficiency by 30-40%, due to
Reducing the speed of passing the mixture through it. However, it is cheaper, easier to install
and can be used as a temporary option. Place installation nozzle or gibler

Making your own is a form for filling foam concrete.
Focobs for foam blocks do it yourself
Molding capacity can be made of any
Material: plywood, metal, plastic. The main requirement, the material should not
Deform in the process of filling the solution.
Making a form involves the passage of two stages:
- calculation forms for foam concrete;
- Production of shape for foam concrete.
How to correctly calculate the size of the foam block form?
Building blocks (walls) are usually produced in suchratio (proportion) Length: Width: Height - 4: 2: 1. Such a ratio
is optimal because it allows the ligation of the row of masonry without
Trim blocks. Thus, if the depth of the form is 150 mm, then its width and length
It will be 300 and 600 mm, respectively.
For the private production of foam concrete blocks, it is advisable
Use a form that allows you to simultaneously make up to 30 foam blocks.
Note, the length length will be longer than the total
Length blocks. This is due to the fact that partitions in the form have a certain
Thickness.
Note. It is better to install partitions in such a way
So that the plane of the greatest area is above. In this way,
Provides faster blocking of the block and a uniform set of strength
Foam concrete. For the same reason, it is not recommended to do multi-level forms.
How to make foam blocks with your own hands?
The process of making the form begins with the bottom device. TO
It is hardly attached side walls and detachable internal
Partitions.
Masters advise to make a form for foam concrete blocks
collapsible. This technique will vary the size of the blocks. For the same reason
Partition plates should not be welded. Better to do in them
Cuts up to half the width and combine through them.
If plywood is used as a material for
making formwork, then you need to fix partitions with nails. Corners, struts and

The advantage of self-made form is the possibility
obtaining foam blocks of non-standard length or configuration.
Note. When making a form of plywood, before filling
It must be tightened with a solid film. Otherwise, plywood pulls
moisture from a raw solution, which will entail the deformation of the shape and distortion
