Аннотация: This article proves the rationality of using ash and slag wastes in construction as an additional binder in the concrete mix. There was a differentiation of ash and slag wastes carried out according to the types, which depend on the various characteristics of the substance (according to the method of production, the CaO content, according to GOST 25818-91, by activity), and a detailed classification was made on this basis. Advantages and disadvantages of introducing ash into the binder on the quality of the concrete mixture have been described. Particular attention was paid to the following technical characteristics of concrete: strength, specific surface area, density, workability, delamination, water loss, water demand. Studies of domestic and foreign scientists describing the effect of ash and slag additives on heavy and cellular (porous) concretes are presented. Recommendations are given on the rational ratio of cement and ash aggregate in the composition of a concrete mixture. Special attention is paid to the chemical composition of the ash, since it is he who determines its behavior in the composition of the binder. The main economic and technical advantages of using ash and slag are considered.
