House of aerated concrete with their own hands

Why do many choose aerated concrete when building a house? Because it has a lot of advantages, namely: the optimal price, good noise and sound insulation, easier installation in comparison with the brick, fire safety. There are, of course, minuses. One of them is the hygroscopicity of aerated concrete, i.e.its ability to absorb moisture. Therefore, when building a house of aerated concrete with your own hands, you need to provide waterproofing and wall finishing to avoid in the future local destruction of this material. All this in more detail in our article.

Foundation

Before starting to build a self-contained aerated concrete house, all necessary calculations are carried out to determine the type of foundation and its depth. The foundation of a house made of aerated concrete must be strong, reliable and thorough. In the photo you can see a monolithic foundation.

Depending on the type of soil, a strip or columnar-grout foundation is also suitable.

Depending on the depth of soil freezing and swelling forces, which can be determined from the soil map of the region, the recommended depth of foundation is determined.

Calculating the width of the base, you need to provide if future work is planned for facing the facade with brick. Ideally, the width of the base should be 5 cm wider than the wall.

When adjusting the height of the plinth, it is necessary to completely exclude the possibility of contact of aerated concrete blocks with melting snow and water on the site.

Masonry of aerated concrete

Before the beginning of works on self-laying of aerated concrete, it is necessary to carry out work on the waterproofing of the basement from the first row of masonry. The plinth is insulated from the aerated concrete masonry with ruberoid or more modern materials. Before the beginning of the laying, the blocks must be dried. The stated strength and thermal conductivity they have in a dry state.

Therefore, during masonry work, aerated concrete blocks must be unpacked immediately before work. Laying should be done on special masonry glue. The use of cement mortar leads to the appearance of cold bridges in the walls, which can cause a rise in the cost of the project due to the need for additional insulation. Each series needs to be reconciled according to the level. Unevenly laid blocks can create uneven stresses, which will lead to the appearance of cracks.

The construction of a house made of aerated concrete provides for the creation of armpoles. To create them, manufacturers produce special hollow blocks with grooves for laying reinforcement. Armopoyas are usually laid in the first row, in each 4th row of the masonry and on top of the window blocks.

Also, it is necessary to strengthen the walls with increased, for example, wind load. It is mandatory zamonolichivaetsya series, after which the laid slab ceiling. If you plan to build a gas concrete house with your own hands, you should definitely study the SNIPs.

The thickness of the internal and external walls and internal partitions is usually regulated by the regulations depending on the terrain in which the construction takes place. Blocks are easily handled: punched, milled, sawed. It is very convenient to provide during the laying installation of reinforcement for fastening window and door openings.

Warming and waterproofing

Additional insulation of walls is usually not necessary. The thermal conductivity of aerated concrete is equal to the thermal conductivity of the tree, in addition it is a breathable material that provides a comfortable indoor microclimate.

Aerated concrete deteriorates the thermal conductivity only when it gets wet. However, it only concerns literally its being in the water for a long time. Normal precipitation does not affect the technical characteristics of the blocks.

For protection against wetting, it is sufficient to correctly install the water disposal system from the house: to make a blind area, peaks and ebbs. The main bridges of cold in the house are window and door openings and a roof. Thermal insulation in these places is done using conventional technologies.

Exterior and interior decoration

For exterior decoration, it is necessary to select vapor-permeable materials that will not prevent steam and moisture from escaping from the inside of the room to the outside. If the site is characterized by long slanting rain, it is better to make a hinged facade, but in this case, you must always provide for the presence of ventilation clearance. For interior finishing use materials with high vapor permeability. Usually, plaster is suitable for these purposes.
