Abstract

An urgent task of the construction industry is the production of effective building materials characterized by high physical and mechanical properties, durability, operational and aesthetic qualities, and low cost. At the same time, special attention is paid to the issues of import substitution, rational use of raw materials and energy resources, the introduction of low-waste technologies, and the reduction of the uncontrolled impact of human activities on the environment. The paper presents the results of research on the effectiveness of the use of an additive based on broken glass in the manufacture of ceramic building materials. The paper considers the directions of using glass waste and conducts a study of the physical and mechanical properties of ceramic materials with an additive based on broken glass. It has been established that the obtained samples of ceramic products with the addition of broken glass meet the requirements of STB 1160-99, the recommended amount of broken glass used as an additive to improve the physical and chemical properties of building ceramics (ceramic bricks for masonry of external and internal walls of buildings and structures) is in the range from 5 to 10 % in excess of 100 % of the basic composition of the mixture. The results obtained indicate the potential to use broken glass as high-temperature additives (melts) in the production of construction and clinker ceramics that meet the requirements of technical regulatory legal acts, to expand the range of construction ceramics and improve the environmental situation.
