FIELD: construction.
SUBSTANCE: dry heat insulating plastered cellular polystyrene construction mixture is described, which includes cellular polystyrene granules, mineral astringent, plastifying additive on the basis of lignosulfonates and water and differs by the fact that contains plaster astringent as mineral astringent, technical sodium lignosulfonates as additive on the basis of lignosulfonates, and additionally contains calcium hydroxide, sodium tripolyphosphate and sodium polycarboxylate with the following ratio of mixture components in wt %: cellular polystyrene granules 2.0-6.0; plaster astringent 91.0-96.0; technical sodium lignosulfonates 0.3-0.4; sodium polyphosphate 0.03-0.2; calcium hydroxide 1.3-1.9; sodium polycarboxylate 0.06-0.13; water - the rest. Also method is described for preparation of abovementioned dry heat insulating plastered plastered cellular polystyrene construction mixture.
EFFECT: increase of strength properties, water resistance, heat insulating properties, lower shrinkage, durability with reduction of material flow rate.
