Abstract
during the implementation of the program to restore the housing stock of the Chechen Republic, as well as during the planned demolition of dilapidated housing, significant volumes of technogenic raw materials were generated, in particular, large volumes of brick and concrete scrap. Enterprises for the production of building materials and products also produce significant volumes of production defects, which accumulate over the years at landfills. Ceramic broken brick and broken brick dropouts are used to fill the roadbed, and the main part still goes to the dump and landfill, which is also an environmental problem. One of the promising ways to use dropouts and broken brick itself is to use them as secondary aggregates in concrete and mortars. This article discusses the issues of improving the quality of ceramic concrete mixtures, choosing the optimal composition and technology for mixing concrete mixtures using dust fractions of dropouts for crushing ceramic brick bricks
