FIELD: building.
SUBSTANCE: composition for making unautoclaved gas concrete contains, wt %: Portland cement 30.7-40.9, ash of thermal power plants 21.5-32.3, calcium oxide 1.62-2.16, aluminium powder 0.098-0.110, used textile cord 0.64-0.97, alkaline and alkali-earth metal chlorides chosen from NaCl, CaCl2, KCl, LiCl 0.15-0.41, naphthalensulfonic acid and formaldehyde condensation product 0.23-0.41, water - the rest. The method for making unautoclaved gas concrete involves preparation of said yielding raw mix with combined pre-grinding of dry components of said mix, except for Portland cement, during 30-40 min, expansion of the raw mix, concretion in steaming or in normal conditions. After combined grinding of dry components, Portland cement is added to the raw mix.
EFFECT: improved handling behaviour of gas concrete and simultaneous simplification of making thereof.
