The strength of plaster coatings depends on the quality of adhesion of the applied plaster layer with the base. The bases for applying plaster coatings are necessarily prepared, the technology of preparing the bases may differ depending on the coating applied. It is established that the closer the initial structures are in structure, the higher the quality of the plaster coating as a whole. According to geonics, the relationship of structures in building composites is based on basic properties, general physical and mechanical indicators, which equally apply to both the building plaster solution and the base. At the same time, a contact binder is allowed between the base and the plaster layer with similar indicators, the presence of which guarantees reliable adhesion and strength of the resulting coating. The use of plaster solutions on enriched fine substandard sands with complex modified additives makes it possible to improve the technological qualities of the mortar mixture, the physical and mechanical characteristics of plaster solutions and optimize the technology of applying the plaster coating. Successive application of plaster layers on technogenic sands with different size modulus allows creating a base rough coating on the base, which closes the main defects and creates the base for the next layer of plaster solution. The Chechen Republic has extensive reserves of very fine and fine local sands, which in their basic properties are inferior to medium- and coarse-grained sands, but with a rational selection of composition, enrichment of grain composition can be used to produce high-quality construction composites. To enrich the grain composition of fine local sands, it is proposed to use dropouts of concrete scrap crushing, the volumes of which are significant on the territory of the Chechen Republic. Dropout of concrete scrap crushing by chemical composition is suitable for enriching local fine sands and when selecting the composition of the plaster solution increases the physical, mechanical and technological properties of the mortar mixture.
