FIELD: construction.
SUBSTANCE: dry mortar for preparation of cellular concrete on the basis of gypsum contains the following components, wt %: gypsum binder 60.0-95.0, modifying additive 4.99-37.0, foamer and/or gasifier 0.01-3.0. At the same time modifying additive has specific surface of 1000-10000 m2/kg, average size of particles of not more than 50 micrometre, hydraulic activity of at least 1 mg/g and contains the following components, wt %: hydraulic binder 50.0-90.0, active mineral component 9.9-45.0, plasticising additive - 0.1-5.0, controller of setting and hardening times 0.1 over 100, stabiliser 1.0 over 100.
EFFECT: simplified production-process cycle of cellular concrete preparation and products from it with simultaneous improvement of physical and mechanical properties.
