FIELD: construction.
SUBSTANCE: invention is related to composition of complex additive for concretes and construction mortars, including the following components, wt %: sodium thiocyanate 2.0-65.0, sodium thiosulfate 10.0-60.0, sodium sulfate 0.1-10.0, sodium carbonate 1.0-10.0; water - the rest. Specified complex additive may also additionally contain sodium ferrocyanide and/or sodium polythionate. Invention is also related to concrete mix, which contains the following components, wt %: cement 9.5- 24.4, sand 24.0-38.0, crushed stone - 42.0-45.0, specified additive 0.05-1.0, water - the rest. Invention is developed in dependant claims.
EFFECT: stabilisation of physical-mechanical properties of complex additive during their storage, higher impermeability, crack resistance of concrete with specified additive, accelerated concrete strength gain, also at lower hardening temperature.
