3 negative disadvantages in aerated concrete houses. Without fixing them
The disadvantages of aerated concrete include its poor vapor permeability. With porous ceramic blocks or expanded clay blocks, vapor permeability will be better than that of aerated concrete!
Due to poor vapor permeability, constant humidity is felt in the house. Therefore, the windows fog up. In no case should the outer walls of aerated concrete be insulated with foam!
Only the unused base of the building can be insulated with foam.
Aerated concrete, material not very resistant to fracture and compression! If the foundation of such a house, for some reason, shrinks, then the load-bearing wall will definitely crack.
Therefore, it is advisable to reinforce the walls of aerated concrete blocks with a masonry mesh.
It should also be borne in mind that when building a house from aerated concrete, in the places of interfloor floors, you will also need to do armopoies around the entire perimeter of the building, since reinforced concrete floor slabs cannot be supported directly on the load-bearing walls made of aerated concrete blocks!
It must be remembered that in the first year of operation, the walls of aerated concrete give a slight shrinkage. In general, in the first year, it is better not to glue the wallpaper!
And also, in the first year of living in such a new house, the smell of silicate (lime) will be felt inside.
There is a special technology textbook from 1953. release for FZU then they began to be called PTU. It says that of all aerated concrete, only expanded clay concrete went to civil construction, and gas and foam concretes were considered harmful because of their components, if memory serves, then aerated concrete is aluminum oxide, and foam concrete is alkaline soap, in any case, residential buildings in the USSR were not built from these concretes.
