COMPOSITE MATERIAL BASED ON ANTHROPOGENIC WASTE AND METHOD OF ITS PREPARATION Russian patent published in 2023 - IPC C04B28/16 C04B22/08 C04B18/04 C04B111/20 

FIELD: building materials.

SUBSTANCE: invention is related to building materials based on technical anhydrite (fluoroanhydrite), which has improved physical and technical characteristics, which can be used in construction of industrial and civil buildings, in construction of interior and inter-workshop walls and partitions. Composite material based on anthropogenic waste includes fluoroanhydrite and water, which is 20% by weight of fluoroanhydrite. The composition additionally includes sodium hydrosulfite and metallurgical dust, while sodium hydrosulfite content is 0.8% by weight of fluoroanhydrite, and metallurgical dust content is 1% by weight of fluoroanhydrite; or the composition additionally includes sodium sulphate and technical sulphur, while sodium sulphate content is 2% by weight of fluoroanhydrite, and technical sulphur content is 15% by weight of fluoroanhydrite. A method for preparing the material is also described.

EFFECT: creation of a structural composite material with improved hydrophysical, physical and mechanical characteristics as a binder in production of which dispersed production waste is used.
