The subject of research is reaction-powder concrete based on Portland cement modified with a complex organo-mineral additive, which includes polycarboxylate superplasticizer and finely divided active siliceous and carbonate components of artificial and natural origin, which allows to obtain concrete with improved performance. The aim of the work is to develop and optimize compositions of high-strength reaction-powder concretes based on Portland cement modified with complex organo-carbonate-silicate additives and quartz sand with carbonate inclusions, which will have improved physical-mechanical and special characteristics and can be used as a high-tech transport facilities, road surfaces. Research methods physicochemical methods, physical and mechanical methods for determining the normal density (TNG) of cements, terms of their hardening, consistency of mortar mixtures, properties of mortars, flexural strength, compressive strength, adhesion strength, chemical shrinkage, autogenous shrinkage, shrinkage of drying, parameters of pore structure).
