METHOD OF PRODUCING NON-FIRED MINERAL BINDER OF HYDRAULIC HARDENING Russian patent published in 2025 - IPC C04B18/04 C04B28/18 C04B7/17 

FIELD: construction.

SUBSTANCE: invention relates to the construction industry, in particular to the production of non-fired inorganic binders from wastes and industrial products of various industries. Method of producing non-fired mineral binder of hydraulic hardening involves grinding, mixing and mixing with water a mixture of an acidic active mineral additive and a lime-containing component. Amount of the active mineral additive added per unit weight of the lime-containing component is calculated by formula AMS = (10±0.4): A_PA × C_CaOact., where AMS is the amount of active mineral additive, g, kg, t; A_PA is the pozzolanic activity of the mineral additive, mg CaO/g AMS, g CaO/kg AMS, kg CaO/t AMS; C_CaOact. – content of active calcium oxide in lime-containing component, wt.%; coefficient ±0.4 corresponds to the confidence interval, which includes results of laboratory experiments with reliability of 95%.

EFFECT: invention enables to reduce specific consumption of components for synthesis of non-fired binder and obtain binder with maximum mechanical characteristics.
