FIELD: production of composite materials.

SUBSTANCE: invention relates to a method of producing composite binder based on industrial wastes, which can be used in cement and construction industry. This is achieved by the fact that method of producing composite binder based on industrial wastes includes grinding of portland cement clinker and industrial wastes, differs by the fact that the industrial wastes used are vanadium production wastes containing the following, wt.%: SiO₂ 3.22; Al₂O₃ 0.41; CaO 36.93; MgO 5.03; V₂O₅ 2.81; Mn₂O₃ 17.39; SO₃ 33.02; other secondary impurities 1.19; colemanite is additionally used of the following composition, wt.%: B₂O₃—40.1; CaO—27.5; SiO₂—5.2; MgO—2.8; Fe₂O₃—0.06; other secondary impurities—24.34; mixing said vanadium production wastes and colemanite at a weight ratio of 2:1, 86–88 wt.% of portland cement clinker is added and the mixture is ground together in a centrifugal planetary mill for 0.25 hours to specific surface area of 6,400 cm²/g.

EFFECT: reduction of energy consumption of composite binder production based on industrial wastes, reduction of binder grinding time and improvement of end product quality.
