FIELD: manufacture of building materials. SUBSTANCE: invention concerns a method wherein blend is prepared from cement, water, and polystyrene, and shaped articles are subjected to thermal treatment. Novelty consists in that first 2 vol parts of cement is agitated with 1 vol. part of water for 15 s to produce gel-like cement binder. Then, with not stopping agitation, 5-10 vol. parts of foamed polystyrene is added. Resulting mix is agitated for further 2 min 45 s to yield desired blend. When shaped, articles are heated at a temperature not higher than 70 C. EFFECT: improved heat insulating quality of material. 1 dwg, 1 tbl
