METHOD OF PRODUCING NON-FIRED MINERAL BINDER OF HYDRAULIC HARDENING Russian patent published in 2025 - IPC C04B7/13 C04B7/28 C04B28/12 

FIELD: construction.

SUBSTANCE: invention relates to the construction industry and can be used in the manufacture of construction products for hydraulic hardening. Method of producing non-fired mineral binder of hydraulic hardening involves grinding, mixing and mixing with water a mixture of technogenic heat-treated silicon-aluminium-containing waste in form of burnt rock of heaps of Cheremkhovsky coal deposit and a lime-containing component, the weight of which per unit weight of the dry burnt rock is calculated by the equation M_Lime=(1±0.05)×12.4:C_{Ca(OH)2 act.}, where C_{Ca(OH)2 act.} is content of active Ca(OH)₂ in lime-containing component, wt. %; and (1±0.05) is a confidence interval in which the results of experiments fit with reliability of 95 %.

EFFECT: invention increases mechanical strength of articles made from binder, reduces specific consumption of burnt rock and lime-containing components, reduces time and energy consumption for drying the entire amount of burnt rock.
