METHOD OF PRODUCING BINDER BASED ON INDUSTRIAL WASTES Russian patent published in 2024 - IPC C04B7/153 C04B7/52 C04B18/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a binding material based on industrial wastes, which can be used in the cement and construction industries. Method of producing binder based on man-made wastes involves grinding portland cement clinker and man-made wastes, wherein industrial wastes used are vanadium production wastes containing, 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; wastes of enrichment of ferruginous quartzites of Kursk magnetic anomaly, containing, wt.%: Na₂O – 0.98; MgO – 5.84; Al₂O₃ – 2.52; SiO₂ – 72.74; K₂O – 0.65; CaO – 3.12; TiO₂ – 0.27; FeO – 9.45; Fe₂O₃ – 4.06; P – 0.65; S – 0.21; and said wastes are mixed with scrap of sanitary construction ceramics at ratio of 3:1:1, adding 84-86 wt.% of portland cement clinker 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 intensity of binder production based on technogenic wastes, reduction of binder grinding time and improvement of end product quality.
