CRUDE MIXTURE FOR PRODUCING BLOCK FOAMED GLASS Russian patent published in 2024 - IPC C03C11/00 C03C6/02 

FIELD: chemistry.

SUBSTANCE: crude mixture relates to production of foam glass material for construction purposes. Crude mixture contains a glass-forming substance in the form of a mixture of a mineral component and scrap glass and a carbon pore-forming agent. Mineral component used is screenings of iron oxide ore from metallurgical production, scrap green container glass is used as scrap glass, and graphite is used as a carbon pore-forming agent. Components are in the following ratio, wt.pts.: scrap green container glass 90–110, iron oxide screenings of metallurgical production 2.5–7.5, graphite 1–1.5.

EFFECT: low foaming temperature, low density, high strength of the obtained material, wider raw material base and recycling of mineral wastes.
