FIELD: chemistry.
SUBSTANCE: invention relates to a composition of a complex additive for concrete mixtures and mortar and can be widely used in production of monolithic and prefabricated structures, mainly for hydraulic engineering structures and road concrete. The complex additive contains the following (pts.wt): superplasticiser S-3 5-50, isopropyl alcohol 10-55, carbamide 5-45. In a special embodiment of the invention, the complex additive contains the following (pts.wt): superplasticiser S-3 10-30, isopropyl alcohol 10-55, carbamide 5-45, ballast salts from desulphurisation of coke gas based on sodium rhodanate and thiosulphate 5-50.
EFFECT: high frost resistance of concrete in layers and high strength of the concrete after 28 days.
