To ensure modern requirements for energy efficiency of buildings and structures, the relevance of the use of effective heat-insulating materials is shown. An important task is to find new ways of obtaining a heat-insulating material — foam glass with reduced energy and resource costs. The results of research on the development of foam glass of the "clay-cullet-sodium hydroxide" system are given. The use of clays is justified by the prevalence and chemical composition. To reduce the average density of foamed glasses, the use of thermal activation of clay rock is suggested, and to increase the strength of foam glass, a partial replacement of cullet with perlite is suggested. The regression dependence of the average density of foamed glasses on prescription and technological factors is obtained. The results of physical and chemical studies of the structure of raw components and foamed glass are presented.
