RAW MATERIAL MIXTURE FOR MANUFACTURE OF NON-COMBUSTIBLE THERMAL INSULATION MATERIAL Russian patent published in 2021 - IPC C04B28/26 C04B38/02 C04B111/20 C04B111/27 

FIELD: construction materials.

SUBSTANCE: invention relates to the construction materials industry, namely to the production of aerated concrete – light cellular concrete with closed pores evenly distributed throughout the entire volume, it can be used for the device of non-combustible thermal insulation of pipelines, thermal units and enclosing structures. The raw material mixture for the manufacture of thermal insulation material contains, wt.%: liquid glass with a silicate modulus of π=2.3-2.6 and a density of 1.23-1.35 g/cm³ 28-32, sodium silicofluoric 3.5-4.5, sodium hydroxide 2.5-3.2, aluminum powder 1.1-1.2, Portland cement 9.0-12.0, crushed glass with a fineness modulus of less than 1.0 10-15, ground glass with a specific surface area of 450-550 m²/kg 28-32.3, water 8-9, while the sum of the components is 100 wt.%, and the ratio between crushed and ground glass is in the range from 1:1.86 to 1:3.23 by weight. The invention is developed in dependent claims.

EFFECT: production of a highly effective and durable thermal insulating non-combustible material with high strength, water resistance, and the disposal of household and industrial waste.
