The monograph presents the results of research on the development of effective materials with fire-retardant properties on the liquid glass base. Sodium liquid glass and other readily available fillers were selected as the main raw materials for obtaining heat-insulating materials. The optimum conditions for obtaining and the ratio of the main components have been determined, the technology of obtaining and the main fire-technical and other characteristics of the materials have been studied.The monograph is designed for researchers, as well as teachers of universities, masters.
