The article presents the peculiarities of obtaining superplasticized cementitious systems "Portland cement – fly ash - superplasticizer" to find a rational provision of the given construction and technical properties of concrete. It was studied the physico-chemical peculiarities of the hydration processes of superplasticized cementitious systems. There were solved problems of directional formation of the microstructure of cement stone. Research results show that the use of superplasticized cementitious systems allows influencing the technological properties and kinetics of structure formation and creating a dense and strong microstructure of the concrete cementitious matrix. The use of superplasticized cementitious systems solves the problems of obtaining rapid-hardening self-compacting concrete, which creates the possibility of using vibration-free technology of monolithic concreting of structures.
