Abstract
The invention relates to the building materials, namely to the composition of polymer-cement mixtures based on technical alkyl resorcinols, containing portland cement as mineral binder. The engineering problem, solved by the proposed invention is the preparation of such mixture, which is hardening in water, is not giving shrinkage, providing necessary strength, having fine adhesion and low viscosity, appropriate in conducting of repairs of underwater parts of mass concrete by injection in cracks with opening 0.5-1 mm.
