What are the projects of houses from aerated concrete

There are enough types of building materials for the construction of the house, but in this case aerated concrete blocks stand aside. Although the construction of housing with their help is not at all complicated than that of a brick, but the technology has its own nuances. In this article we will talk about what are the projects of houses made of aerated concrete with an attic and without, and what is their advantage over other types of building materials.

General information

Так как блоки хорошо впитывают влагу, они нуждаются во внешней защите, что можно причислить к негативу. А, вот в соотношении цена и качество другие конструкционные материалы им проигрывают (см.также статью «Рассмотрим все плюсы и минусы газобетона»).

Therefore, projects of country houses from aerated concrete and for year-round living are in good demand among consumers, giving the opportunity to significantly reduce material costs, leaving the quality at an acceptable level.

In addition, there are other advantages of the material:

• fire safety;
• environmental friendliness;
• the ability to maintain with the help of ventilation microclimate in the room.

Another important advantage of aerated concrete is that a strong foundation is not required, since the weight of the material is relatively small. In addition, the base can be made on weak soil.

Tip: when calculating the foundation, always leave a margin of safety for the future building to prevent ground movement, which is why cracks in the bearing walls sometimes occur.

Mortar or glue

The projects of one-story houses of aerated concrete, like any other can not do without walls. For their construction using a solution of sifted cement and sand or special glue.

The latter makes it possible to create a mating seam with a thickness of only 3 mm. During laying it is better to use a toothed comb, which allows you to evenly distribute the composition.

According to experts, the projects of two-story houses of aerated concrete are designed for year-round construction. Special brands of glue have been developed that allow the mixture to keep its adhesive and plastic properties up to –15? С.

Tip: if the project of a residential building of aerated concrete involves the use of sand-cement mortar, antifreeze additives should be introduced into it at low temperatures.

Usually, aerated concrete blocks are brought in finished form to the construction site. However, it is possible to save money on their production by making a material with your own hands in the conditions of a household.

For this you need to prepare:

• sand;
• cement;
• aluminum powder, it is she who after combining with calcium oxide hydrate begins to release hydrogen.

The process instruction is simple:

1. After the mixture is poured into the gas concrete mixer, it should be thoroughly mixed there.
2. At the second stage, it is evenly distributed into prepared forms of metal, taking into account that after some time it will “swell up” and fill the form completely.

To work, you will need to buy forms and betonosmesitel. However, as practice shows, these costs will fully pay off during the construction of a single house.

Do not forget that aerated concrete walls have the ability to "breathe", so for their cladding it is better to choose siding or sandwich panels. If you decide to plaster them, give preference only to those mixtures that are intended only for aerated concrete and have high vapor permeability.

Main characteristics

Due to its low cost, the wall aerated concrete blocks are gradually replacing traditional building materials. This also contributes to the ease of operation and good performance.

Consider some:

Additional properties

Aerated concrete blocks have proven their reliability in construction:

• warehouses;
• buildings;
• industrial buildings;
• wall ceilings;
• fences.

With their help, you can carry out the insulation of ready-made objects.

One of the features of the material - do not burn, even when in an open fire for a long time. For example, it is able to withstand temperatures up to 1200? С, which is 2 times higher than the temperature in the structure during a fire.

But, most importantly, the blocks do not lose their properties. It is enough to clean them of soot and can be reused in construction work.

Experts say that from an environmental point of view, aerated concrete is absolutely safe for our body, in this parameter it is second only to wood. But, if we take into account that the latter cannot be found in its pure form, since it is covered with weeds, impregnations, paints and varnishes that emit volatile substances, aerated concrete in this case goes to world leaders.

The house of this material is completely devoid of such troubles as:

• dampness;
• mold;
• fungus.

Due to the closed pores, moisture can not penetrate into the room through it, so it maintains constant humidity. Among the disadvantages of building materials should be allocated its reduced strength when bending and stretching. Because of this, small cracks may appear on the walls.

Conclusion

Choosing projects of aerated concrete houses with or without a bay window, you get housing, in which there are practically no flaws. It will never be too wet or dry, so that the body will never feel discomfort.

At the same time, before starting construction, it is better to consult with experts about the main issues, in particular, about the soil and the foundation.
