FIELD: chemistry.
SUBSTANCE: invention relates to production of concrete aggregates. In the method of producing coarse aggregate for concrete, involving depositing a layer of a mineral binder-based mixture onto the surface of an aggregate, followed by hardening thereof, the aggregate used is blast-furnace slag chips and the mineral binder-based mixture is a portland cement-slag and sand mixture, which is obtained by grinding blast-furnace slag, taken in weight ratio of 1:3-1:2, with water-to-cement ratio of 0.8-1.2.
EFFECT: high adhesion of the aggregate to hardened cement paste of the concrete.
