FIELD: building materials. ^ SUBSTANCE: invention proposes a mixture comprising the following components, wt.-%: low-molecular polybutadiene, 8-12; sulfur, 3.0-5.0; thiuram, 0.4-0.6; Captax, 0.1-0.2; Altax, 0.15-0.25; zinc oxide, 2.0-3.0; calcium oxide, 0.3-0.7; fly ash from the central heating and power plant, 6.0-10.0; quartz sand, 21-28, and granite crushed stone, the balance. The mixture provides the possibility for preparing the composite showing higher chemical stability in hydrochloric acid and nitric acid solutions. After 3 months keeping in 36% hydrochloric acid solution is increased from 0.69 to 0.72. Invention can be used in making chemically stable, high-strength articles and constructions. ^ EFFECT: improved and valuable properties of mixture. ^ 2 tbl, 1 ex |
