FIELD: building.
SUBSTANCE: invention refers to building materials, particularly to additives of poly-functional action for cement concrete. Additive contains block-copolymer of poly-methylene-naphtalene-sulphonates and ligno-sulphunates produced in reaction of poly-condensation of oligomeric poly-methylene-naphtalene-sulphonates and process ligno-sulphunates at their weight ratio equal to 1: 0.10-0.30 and technical ligno-sulphunates at the following ratio of components, wt shares: the said block-copolymer 1, process ligno-sulphunates 0.5-1.5.
EFFECT: increased strength of concrete at maintaining plasticising effect Invention is developed in dependent points of formula.
