FIELD: building industry, in particular raw mixtures for production of heat-insulating materials for heat insulating of roofing, building walls, floor, etc.
SUBSTANCE: claimed mixture contains (mass pts): expanded polystyrene foam granules 10-12,5; cement 100-170; and water 80-100; and additionally polymethylenenaphthalene sulfonate 0.8-0.85; and sodium sulfate 0.01-0.08, wherein said granules are obtained by surface treatment of polystyrene with aqueous solution of polymethylenenaphthalene sulfonate and sodium sulfate.
EFFECT: increased cement adhesion to polystyrene foam without application of toxic and expensive additives; decreased component number without losses of heat-insulating properties.
