FIELD: chemistry. ^ SUBSTANCE: invention relates to making facing-decorative and construction products, specifically to a polymer silicate-concrete mixture for making facing-decorative and construction products. The polymer silicate-concrete mixture contains the following in wt %: liquid glass 10.5-15.5, sodium silicofluoride 1.6-2.5, polymer additive in form of unsaturated polyester resin based on terephthalate 0.6-1.3, surfactant - polyoxyethylene glycol ether of synthetic primary higher alcohols of the C12-C14 fractions 0.1-0.25, powdered quartz - marshalite with specific surface area not less than 500 m2/kg 24.5-25.5, quartz sand 24.0-26.0, broken stone - the rest. The quartz sand and broken stone of different types in ratio of (0.7-0.85): 1 is the complex filler. ^ EFFECT: improved strength properties, water resistance and softening coefficient of decorative-facing and construction products, reduced water absorption. ^ 1 ex, 2 tbl |
