construction of foam concrete and aerated concrete

Disadvantages of the technology of construction of foam concrete and aerated concrete .

– High moisture – aerated easily absorbs moisture, which leads to lower comfort at home , disruption microclimate and deformation of the material . To eliminate such effects have also organize an expensive range of engineering activities ( sheathe house additional materials, install a powerful system of ventilation and air conditioning ) .

As a result , either have to accept a reduced level of comfort and safety of the building, or significantly increase the overall cost of construction .

– Limiting insulation – gas and foam materials are indeed capable of providing high thermal and sound insulation . However, construction companies fail to say is that for such high performance is needed very specific category of porous concrete , with a density of not less than D500. At the same time , this brand of cellular concrete is the maximum density of the proposed construction companies .

That is, it is likely that you simply ” slipped ” gas-or lower-density foam , promising admirable insulation, stuff like that just can not provide .

– Low mechanical strength – because of the structure of porous concrete is strong enough material to the horizontal or vertical loads , but if necessary to fix anything in the gas or foam concrete blocks , you will inevitably come across a flowability of the material , otherwise known as , low mechanical strength .

Accordingly , the use of conventional fasteners may be not only ineffective , but harmful to the wall material . You have to use a special hardware for these materials , the value of which (on average) is 5 – 6 times higher than the cost of conventional fasteners.

– The presence of thermal bridges – gas and foam concrete blocks are bonded with mortar , which creates uneven seams to 10 mm thick. Such masonry is not only the cause of irregularities of the walls ( since one unit is slightly higher than the other – just below , and on the background of the entire wall height difference is noticeable ), but also the so-called thermal bridges , which greatly reduces the thermal insulation properties of the structure. As a result, the house has all the chances to get and uneven, and cold.

For comparison , polystyrene blocks are bonded with a special adhesive that creates a thick seams (! ) Of 4 mm, which completely eliminates the possibility of the formation of cold bridges .

– Thickness of the walls – if you carefully peruse the state standards , it is clear that the alleged construction companies sufficient thickness of the walls of the gas or foam calculated based on the dry weight of the components . But the manufacture of blocks of the water is added , and it is completely (which is natural ) does not evaporate . In turn, the presence of any water in the building thermal insulation material reduces the parameter .

Thus, if you hold the correct calculations , it turns out that the traditional laying of 380 mm is insufficient to ensure the comfort of home. Will be the optimal wall thickness of 640 mm . Meanwhile , most companies use blocks of not more than 500 mm thick.

– Higher cost of compliance with building codes and state standards – in the previous paragraph logically follows that to build a comfortable and safe housing must be ordered at all those units that are so advertise construction companies. Accordingly , blocks of greater thickness and the cost will be more expensive. Thus , saving construction (compared to brick wall ) is reduced by 10 – 20 % compared with the figures declared by construction companies .

– Accelerated corrosion of the metal components of the walls – brickwork in cement mortar contributes to the formation of residual free lime , which leads to corrosion damage to valves, pipes, frame , and other metallic inclusions wall.

And here again it should be noted styrofoam -like material that is not sealed by masonry mortar , and special glue, absolutely neutral to metal structures .

– The need to bookmark monolithic foundation – is traditionally celebrated lightweight cellular concrete , and then colorfully painted opportunities for the construction of houses for the most inexpensive and light forms the foundation. However builders apparently “forget” report that gas and foam easily with minimal cracking or deformation of the displacement of the foundation. Therefore tape option, of course , you can lay , but only tape monolithic , and it is not so cheap. Or you have to put up with the risk of cracking walls. But the benefit to such ” savings” ?

So the result is that once construction technology of gas and foam were indeed profitable and popular due to the lack of better methods of construction. However, today they are not only ineffective , but also at a loss as construction companies (trying to regain its former popularity materials ) often exaggerate or underestimate the actual characteristics of cellular concrete in order to attract customers.
