The article is devoted to the study of the possibility of reducing the consumption of cement in concrete by optimizing the fractional composition of small aggregates of natural and artificial origin and the use of ash and slag waste of thermal power plants. Using the computer program of the grain composition correction module allows you to quickly determine the rational composition of sand and ensure tight packaging of its grains in concrete. In addition, optimal quantities of hyperplasticizers were selected to produce concrete with the required physical and technical characteristics.
