STRUCTURAL AND HEAT-INSULATING CONSTRUCTION MATERIAL Russian patent published in 2025 - IPC C04B28/24 C04B14/10 C04B16/02 C04B18/04 C04B35/634 

FIELD: construction materials.

SUBSTANCE: invention relates to construction materials, particularly to composition of a crude mixture for preparing construction material used in production of structural heat-insulating articles, as well as for low-rise construction. Structural heat-insulating construction material is obtained from a composition which includes a main component, a binding component and a filler, which are mixed and maintained in a temperature mode with subsequent cooling. Material additionally contains a facing-insulating component, which is a heat-resistant transparent polymer material in the form of a panel. Main component is expanded clay gravel, the binding component is low-melting clay, which are taken at the following ratios: expanded clay gravel from 40 to 60 wt.%, low-melting clay – the rest. Filler is represented by sawdust of microscopic size, or fluffed wastes of worsted and cloth and cotton factories, or post-harvest chaff from fields, which is taken in amount of 0.3 to 20% of weight of low-melting clay. Heat-resistant transparent polymer material is taken in amount of 0.2 to 3% of weight of mixture of expanded clay gravel and low-melting clay.

EFFECT: high strength of the structural and heat-insulating building material, including mechanical strength, high frost resistance and durability of the construction material, high hydro-, sound- and heat-insulating properties of the material, high environmental friendliness thereof during operation, resistance to atmospheric effects, as well as expansion of the range of structural and heat-insulating construction materials.
