FIELD: chemistry.
SUBSTANCE: invention relates to industry of building materials, in particular, to production of concrete mixtures for production of products (plates, wall boards), which are subjected to glazing. Concrete mixture contains, wt %: slag-Portland cement 25-30; crushed for passing through net No20 blast furnace slag 68.5-73.5; mineral fibre cut into 10-20 mm segments 1-1.5, with water-cement ratio 0.5-0.55.
EFFECT: reduction of product durability loss in glazing.
