FIELD: manufacture of building materials.
SUBSTANCE: invention relates to manufacture of heat-insulation materials and may be used in manufacturing effective heat-retention structures of buildings and constructions using both prefabrication and cast-in-place techniques. Composition contains, wt %: binder 50.1, polystyrene aggregate 1.03, foaming agent 0.3, pore-forming agent 0.01. and water- the balance. Binder is comprised of Portland cement M 400, gypsum G 5, and diatomite taken at ratio 6:1.5:1. Polystyrene aggregate represents foamed granular fraction 0.2-0.4 mm; foaming agent is synthetic substance "Penostrom"' and pore-forming agent is aluminum powder.
EFFECT: reduced heat-conductivity and average density of finished articles.
