COMPLEX ADDITIVE TO CONCRETE MIXTURES AND MORTARS

摘要

Еру invention relates to the building materials. The complex additive contains mixture of salts based on sodium thiosulphate and rhodanate and as organic component amkiros and sodium polynaphthalene sulphonate (superplasticizer С-3) in such component ratio, mass %: salt mixture based on sodium thiosulphate and rhodanate 50-98, amicro 3 1-40, superplasticizer С-3 – the rest. The additive provides the increasing of mobility of concrete and soluble mixtures, increasing strength, freeze resistance and water permeability of concretes and mortars.
