Aerated concrete - a cellular concrete or artificial stone with closed spherical pores with a diameter of 1-3 mm.Made of aerated cement, silica sand or industrial waste ash and slag, lime with the addition of blowing agent in the form of aluminum powder.

In the dry mixture under pouring water causes a chemical reaction between lime and aluminum powder with hydrogen.The mixture thus increases at a rate similar to the test.After the start of the curing mass can be chopped into blocks, plates or panels.Then there is the ultimate cure.The resulting material, which eventually becomes harder, easily processed and does not burn.

to build a house of aerated concrete, it is necessary to know the advantages and disadvantages of the building material.The merits of greater than the disadvantages, and they include:

• manufacturability - the unit can be easily cut with a hacksaw;
• low weight - the unit weighs about 36 kg and 15 bricks - 52 kg.Laying is performed on a special adhesive mixture which is much easier to grout;
• precise dimensions and a smooth surface - the plaster cast do not need, you can simply sanded;
• excellent heat and sound insulation.The air trapped in the voids will be the best insulation.

Deficiencies have been little studied, because the material is relatively recent.These include the formation of cracks along the blocks, high water absorption, brittleness and poor retention of dowels.

Preparing for the construction

Aerated concrete is gaining in popularity, and if we are building a house of aerated concrete, then it is not exclusive, but universal practice.The construction can be carried out at temperatures from +5 to +25 ° C, if the air is warmed up, ready to constantly moisturize aerated water.

Aerated concrete with their hands to make easy.On the ground you need to lay roofing felt on top form to put the right size, shape wall wipe working off inside.Cover the dry mixture, mix well and pour the water slowly while continuing to stir.When the mixture is "rises" and the slightly cured, the form must be removed and leave the blocks in place.

After 12 hours, your attempts to make their own hands aerocrete succeed, you need to move the bricks ready for the canopy and let stand for at least a day.Thereafter, they can be stacked.Calculation of concrete blocks made from such considerations that 1 unit replaces 14-15 bricks.To use the tools necessary to prepare:

• woks and carriage for adhesive application;
• saw with hard metal teeth;
• rubber hammer;
• wall chaser;
• square cutting at a right angle;
• grater with metal teeth;
• coarse sandpaper.

makes the house of aerated concrete with their hands

Construction of aerocrete home should start with consultations with local geodetic service.Specialists will determine the level of groundwater and freezing.Aerated concrete absorbs moisture, and need a good waterproofing.What is the foundation needed prompt surveyors, but on top of the foundation is required to fit a layer of waterproofing overlap.Be sure to make a blind area in order to prevent unnecessary water retention.

top of waterproofing applied a thin layer of cement to the alignment, and then stacked aerated concrete blocks made with their own hands.The first series has a special meaning, it sets the correct stacking all the walls.It must be laid perfectly flat, it should be checked on a level or a laser device.

When the first number reaches the angle, it is necessary to saw the exact size of the remaining distance finishing accessories unit, lubricate the end surfaces of glue and adjust the position of the entire structure with a rubber mallet.

After laying each row of blocks of the entire surface to align the teeth with metal grater to remove the smallest level changes.If you do not, in laying stress concentration is formed, and in these areas there are vertical cracks.

Laying concrete blocks is carried out so that the level and evenness observed in all ranks as accurately as possible. It's easy - all sawed and cut very easily.It is important that the blocks were the most fit, because aerocrete masonry done with minimal use of adhesive.

In areas of adhesive joints heat loss is higher than on the surface aerated concrete, and these places are trying to make as thin as possible.Window and door openings should be reinforced with overlapping elements, by the way, in the sale is ready jumpers.Laying of concrete blocks in combination with the jumpers design gives greater strength.The walls are made of concrete blocks are completed prefabricated monolithic slabs of concrete or aerated lungs reinforced slabs.
