FIELD: chemistry.
SUBSTANCE: invention relates to construction materials, which can be used for production of constructive-heat-insulating cellular concretes of non-autoclave hardening. Mixture for preparation of constructive-heat-insulating cellular concrete, includes Portland cement, silica filling agent, consisting of natural sand and active mineral additive, foaming agent and water, as silica filling agent it contains product of combined dry milling of natural sand and silica gel with the following ratio of mixture components, wt %: Portland cement 50-55, natural sand 42.5-48, silica gel 2.0-2.5, water W/S ratio 0.5-0.55, foaming 3% of water volume. As foaming agent mixture contains synthetic foaming additive PB-2000, or PB-lux, or Benotech PB-S.
EFFECT: increased strength with inessential increase of average density, increased coefficient of constructive quality of cellular concrete.
