The active use in the production of building materials of waste after the renovation of housing is a relevant and promising direction. the load on logistics for the supply of inert materials is reduced, landfills and waste storage sites are being destroyed, and the cost of building materials from recycled materials is being reduced. The use of recycled clay bricks allows to solve the problem of solid waste disposal, but also to reduce the environmental damage caused to the environment by mankind from the excessive development of natural resources. Finely ground brick cullet has pozzolanic properties and can be used as an additive in a cement mixture, and a large fraction is used in aggregates of cement compositions.
