The paper proposes a new foam based on cement and the steelmaking slag, which is obtained and developed at the Department of construction materials and special technologies, IAIS VSTU. The purpose of the survey was to obtain an effective insulating material for wall building envelopes, in high-rise housing construction and of the material for use in low-rise construction in the manufacture, which would maximize the use of local raw and production resources. When selecting components, special attention was paid to the resource base of existing enterprises of Volgograd, analyse the products of local manufacturers. The tests were conducted in the laboratory and on the production line. It is known that the slag used in the production of building materials rarely, usually just transported to dumps by truck. At the plants, open hearth plants, slag with shlakovoza buckets are taken and poured as a melt into slag pits. Use water spraying for crushing slag due to thermal shock when the temperature drops.
