FIELD: building. ^ SUBSTANCE: invention concerns production technique of building materials and can be used at obtaining of wall structural material. In the method of manufacturing of plaster products by mixture of the technogenic two-water plaster levigated to a specific surface of 3000 cm2/g and 9000 cm2/g, with the additive of slaked lime and water at their following parity, accordingly, wt %: the two-water plaster levigated to a specific surface of 3000 cm2/g, 37.9325 - 40.3325, the two-water plaster levigated to a specific surface of 9000 cm2/g, 48 - 50.4, water with the additive of slaked lime the rest, with the subsequent pressing, after product pressing dry up to constant mass then maintain them within 15-20 minutes in a water solution of polyvinyl spirit concentration 5 - 10 % and repeatedly dry up to constant mass. The invention is developed in dependent points of the formula. ^ EFFECT: durability and water fastness increase. ^ 3 cl, 3 ex, 1 tbl |
