Zusammenfassung:	FIELD: manufacture of building materials. SUBSTANCE: water-based molding blend contains 67.7-69.2% Portland cement, 0.17-0.21% superplasticizer (S-3), 0.17-0.21% foaming agent, polystyrene filler, and additionally 0.055-0.10% sodium thiosulfate as hardening accelerator, said foaming agent being based on anionic surfactants of the PB-2000 type and said polystyrene filler being polystyrene foaming waste fraction no larger than 1 mm taken in amount 0.6-0.75 cu.m per 1 cu.m of molding blend or mixture of above-indicated fraction with foamed polystyrene fraction no larger than 5 mm used at ratio (4-5): 1. EFFECT: reduced density of polystyrene foam/concrete products. 3 cl, 1 tbl
