FIELD: construction.
SUBSTANCE: gypsum cement pozzolan composition includes portland cement, calcined gypsum, pozzolan additive - metakaolin, as a modifying additive - composition consisting of the following, wt %: carboxylate polyester "Ethacryl™ HF" - 76.7-77.1, controller of setting and hardening times "Best-TB" - 17.7-18.1, polymethylhydrosiloxane - 5-5.4, at the following ratio of components, wt %: calcined gypsum 53.5-53.8, portland cement 14-14.14, modifying additive 2.6-3.0, metakaolin 1.3-1.44, water - balance.
EFFECT: extended timing for mixture setting, giving it self-compacting property, increased bending and compression strength, increased coefficient of softening and reduced water absorption of gypsum-cement pozzolan composition.
