DEVELOPMENT OF OPTIMAL COMPOSITIONS OF NON-AUTOCLAVED AERATED CONCRETE BRANDS WITH AVERAGE DENSITY OF D500, D600, D800

The optimal (for the maximum compressive strength and minimal consumption of cement) ratios of the components, mineral and chemical additives are stated: the ratio of mineral powder and cement MT / D = 1.3, silica fume content of 9 %, the C-3 ? 0,6 %, NaCl ? 0.5 %; optimal laboratory compositions of non-autoclaved aerated concrete with reduced cement consumption of brands with an average density of D500, D600 and D800 are developed.
