METHOD FOR PRODUCING GLASS-ALKALI BINDER Russian patent published in 2022 - IPC C04B28/26 C04B40/00 C04B111/27 

FIELD: building materials.

SUBSTANCE: invention relates to the industry of building materials and can be used in the manufacture of fireless, non-autoclave and cementless binder. The method for obtaining a glass-alkali binder includes grinding the components, molding the mass, natural hardening in the mold until the stripping strength is reached, heat treatment, while breaking window and/or container glass with a fraction of not more than 5 mm in the amount of 80.5-84.6 wt.% is crushed together with an aqueous solution of caustic alkali and hyperplasticizer Melflux 2651 F, prepared in a ratio of 100:15:1.2 - water:caustic alkali:hyperplasticizer Melflux 2651 F, in a ball mill for 6 hours to a specific surface of 500-550 m²/kg.

EFFECT: increasing the mechanical strength and water resistance of the binder.
