FIELD: chemistry.
SUBSTANCE: additive composition in aqueous phase is added to the binder, where the composition contains calcium carbonate particles having average size of 2-200 nm in order to obtain an aqueous suspension, and if needed, mineral filling materials are added to this suspension in order to obtain curing plaster or concrete mixture. Besides calcium carbonate, the additive composition can also contain calcium hydrocarbonate and metakaolin clinker. The invention is developed in subclaims.
EFFECT: improved properties of products bound using hydraulic binder, and easier preparation of concrete and plaster, high frost resistance and faster strength gain.
