Foam concrete block is rather young construction material which has got wide popularity among persons interested to construct cottage or cozy country house. At such competitive advantages as ease, availability of the price and high ecological qualities, foam concrete block possesses number of very essential minuses.
Pluses
On construction terms the houses from foam concrete block practically do not have equal. Without laying of the foundation the construction of the house can be completed for several months. Foam concrete block practically does not shrink. Thanks to ease of construction material the economy of funds for the base is reached. The same physical characteristic has a positive impact on labor costs – to work with foam concrete block more conveniently and quicker, than to put brickwork.
Important plus of foam concrete block – warm and sound insulation. In the house the pleasant microclimate promoting comfortable stay is all the year round formed of this material. Special role in it is played by the simplest composition of foam concrete block which represents concrete mix with small amount of the chemical impurity which are not allocating poisonous evaporations.
The plain formula of structure predetermines the cost of this construction material. It really favourably differs from the pro-thinned-out bar or brick.
Minuses
Foam concrete blocks have honeycomb in the form of air bubbles. Places of the greatest congestion of such "time" can become zones of extra risk because over time even at the minimum external influence in these areas cracks can appear. Such unpleasant signs of destruction are formed practically on all foam concrete blocks regardless of quality of material sooner or later. On degree of durability they cannot be compared to brick or bar. However and it is possible to smooth this shortcoming if to consider weather conditions when choosing the project, giving preference to those decisions which provide strengthening of external walls.
It is important to remember that the structure of foam concrete block is some kind of sponge absorbing moisture from the environment. That walls did not collapse from the absorbed liquid, it is not necessary to save on cement glue with waterproofing properties for laying of blocks.
It is possible to refer to minuses as well special fragility of foam concrete block which is shown not only in use at home, and even at transportation stage on building site. Excess vibration can lead to clinking. Having found the foam concrete blocks which have collapsed on trip, it is necessary to study in detail all party and also the attached documents of compliance. Most likely they rejected.
