FIELD: chemistry.
SUBSTANCE: invention relates to construction materials, specifically to compositions of complex additives for concrete mixtures and mortar. The complex additive for concrete mixtures and mortar contains the following, in wt %: hardening accelerator 20.0-99.5, plasticiser 0.5-80, where the hardening accelerator contains the following, in wt %: mixture of salts based on sodium rhodanate and thiosulphate 34.0-99.0, formate 0.5-33.0, sodium acetate 0.5-65.5. The invention is developed in subclaims.
EFFECT: high mobility of concrete and mortar, high strength and frost resistance of concrete, low freezing point of the liquid phase in mortar.
