Influence of Recipe Factors on the Structure and Properties of Non-Autoclaved Aerated Concrete of Increased Strength

At present, the load-bearing enclosing structures of buildings and are designed built considering increasing requirements for energy efficiency saving such structures. This is due to need a thrifty attitude consumed strive greening construction increase In this regard, one most effective proven building materials cellular concrete. The purpose study was influence some prescription factors on structure formation properties non-autoclaved aerated concrete with improved characteristics. Standard test methods were used, as well SEM analysis Non-autoclaved replacement part cement microsilica in an amount from 4% 16% MS showed higher strength characteristics compared concrete, where replaced by addition granulated blast-furnace slag complex additive. maximum value compressive recorded addition. largest coefficients constructive quality observed compositions silica fume 11% 46% control composition. makes it possible achieve improvement thermal conductivity (up 10%). Replacing additives does not have significant effect conductivity. obtained dependencies confirmed studied at micro level. An microstructure comparison samples composition has been proven.
