We use in the construction of aerated concrete blocks: dimensions and some disadvantages of the material

Today, the real boom is experiencing productionfoam concrete. In many ways, this is due to a sharp rise in price of traditional building materials like brick. Managers of construction companies vied about this material, advertising unprecedented technical characteristics. But are gasconcrete blocks good? Their dimensions are positioned as a virtue, but is it really so smooth?

Recall that aerated concrete is obtained from the mixturecement, aluminum powder, special additives and water, which in the process of autoclaving get rid of excess moisture. The difference in different grades of this material is only in the types of foaming modifiers used. In this same is one of its main advantages: by correctly selecting additives, it is possible to obtain aerated concrete blocks (the dimensions of which can also be individual) with strictly prescribed properties.

About the height of the erected buildings ...

If you take the popular brand D500, then quiteactually build buildings up to three floors. The carrying capacity of the material for this is quite sufficient. But there is one important nuance ... To ensure that nothing unforeseen has happened, ideally it is necessary to thoroughly reinforce those places in which the slabs are supported on the wall of gas blocks. But most often the standard brickwork is used. What's so scary? After all, we have already said that gas-concrete blocks (the dimensions of which allow such a thing to be done) are quite resistant to mechanical influences!

In fact, it turns out that such reinforcingelements are transformed into a kind of cold bridges, the warmth along which they leave the house. In addition, for buildings in three floors it is better to use special reinforced grades of aerated concrete, the thermal conductivity of which negates all their advantages. Do not forget also that this material has almost zero strength when subjected to mechanical impact on the bend.

The slightest miscalculation in the foundation pouring is capable ofturn into major problems. By the way, it is the aerated concrete blocks, the sizes of which are larger than the standard ones, in this respect are the most problematic: they should be installed with jeweler precision, otherwise they will not be chipped.

That's why to say that whenconstruction of this kind of house can save a lot on the construction of the foundation, it is not worth it: just in this case you have to fork out for a capital solid foundation. In the case of the slightest doubt in the properties of the soil will have to fill in the foundation slab, the cost of which can easily cross out all your savings. That's why you should not contact those construction companies that promise to make a house of foam concrete "fabulously cheap".

All aerated concrete blocks, dimensions (weight including)which are slightly less or more than standard values, will in any case give a draft, the consequences of which will repeatedly worsen the bad foundation. In such cases, simple cracks on the walls can not be escaped.

Thus, when choosing a building materialyou should fully weigh the pros and cons. It is very important to acquire them only from those companies that have in practice proven their ability to make high-quality aerated concrete blocks. Dimensions (price, too), they can vary greatly depending on the manufacturer, but when buying, pay attention to the ideal geometric correctness of their shape. Do not take blocks, the cost of which is less than three thousand rubles.
