COMPLEX ADDITIVE TO CONCRETE MIXTURES AND MORTARS

摘要

The invention relates to building materials. The complex additive to concrete mixtures and mortars contains salt mixture based on sodium thiosulphate and rhodanate, dicarboxylic acid and amicro in such component ratio, mass %: salt mixture based on sodium thiosulphate and rhodanate 50-98; dicarboxylic acid 1; amicro – the rest. The additive provides the increasing of mobility of concrete and soluble mixtures, increasing of their strength and freeze resistance of concretes.
