FIELD: process engineering.
SUBSTANCE: invention relates to construction materials used in production of reinforced concrete articles. Proposed method comprises mixing chemical additive and mineral component. Preparation of modifier is performed by pre-absorption dry application of chemical additive Melflux 2651F on surface of mineral component pre-minced to specific surface of 300-700 m2/kg in joint dry milling in ball mill for 15-60 min, or discrete distribution of said additive Melflux 2651F on the surface of said mineral component in joint mixing in gravity-type mixer for 15-60 min.
EFFECT: better physical and process properties.
