LIGHTWEIGHT FIBER-REINFORCED CONCRETE BASED ON INDUSTRIAL WASTE Russian patent published in 2022 - IPC C04B38/02 C04B38/10 

FIELD: construction materials.

SUBSTANCE: invention relates to the field of construction materials, namely to lightweight fiber-reinforced concrete based on industrial waste, and can be used for the manufacture of prefabricated and monolithic reinforced concrete products. Lightweight fiber-reinforced concrete based on industrial waste, prepared from a mixture containing, vol. %: Portland cement 37, river sand with a size modulus of 1.4-1.6 24.75, regenerate slag sand with a size modulus of 0.6–0.7 7.75, a fiber modified in a solution of water and liquid glass or in a solution of water, liquid glass and slaked lime on the basis of textile waste 1,2, a complex pore former, including the dust of the gas purification of the metallurgical plant, containing aluminum oxide, liquid soap and water, 29,3.

EFFECT: increase in the mechanical strength of lightweight fiber-reinforced concrete, industrial waste disposal.
