FIELD: chemistry.
SUBSTANCE: invention relates to composition of binding agent and can be applied in industry of construction materials for manufacturing concretes. Binding substance includes Portland cement, ground granulated blast-furnace slag, silica-containing amorphous component - dust of electrofilters from ferrosilicium smelting, "aqua vitae", enriched by OH- ions with pH=10-11, with the following component ratio, wt%: Portland cement 73.4-76.8; ground granulated blast-furnace slag 18.4-19.1; amorphous microsilica (wastes of ferrosilicium smelting) 3.5-7.4; superplasticiser "Relamix" type 2 with pH 9±1 0.6-0.8; "aqua vitae" with pH=10-11 (above 100% of dry mixture) 1-1.5.
EFFECT: increase of compression resistance at the age of 28 days, reduction of binding substance cost.
