FIELD: construction.
SUBSTANCE: invention relates to the construction materials industry, in particular to the production of fine-grained concrete. Crude mixture for manufacturing fine-grained concrete contains, pts. wt.: Portland cement 24–26, quartz sand 74–76, soaked before swelling in a 3 % aqueous solution of hydrogen peroxide and sodium polyacrylate 0.1–1.5 ground to form a gel-like mass, water 12–14.
EFFECT: higher strength of fine-grained concrete.
