FIELD: binder composition.
SUBSTANCE: invention can be used in production of building composites for manufacturing concrete. The binder includes components in the following ratio, in % by weight: granulated blast-furnace slag (250-300 m2/g) - 30; blast-furnace crushed stone dust (300-350 m2/g) - 20; portland cement (350-400 m2/g) - 50.
EFFECT: increase in compressive strength after 28 days, a decrease in the cost of the binder.
