FIELD: building industry and materials.
SUBSTANCE: invention relates to a composition of complex additive for concrete mixture. The complex additive for concrete mixture comprising a plasticizing agent of naphthalene-formaldehyde type, technical lignosulfates and neutralized air-absorbing resin or saponified wood resin involves C-3 as indicated plasticizing agent in the following ratio of components, wt.-% (as dry matter): C-3, 60-98; technical lignosulfates, 0.05-25; neutralized air-absorbing resin or saponified wood resin, 0.05-6. Invention provides enhancing concrete strength after steaming. Proposed complex additive can be used in manufacture of concrete and ferroconcrete articles and constructions.
EFFECT: improved and valuable properties of additive.
