METHOD OF PRODUCING HEAT-INSULATING STRUCTURAL MATERIAL Russian patent published in 2017 - IPC C04B28/26 C04B40/02 C04B111/20 

FIELD: chemistry.

SUBSTANCE: in a method of producing a structural and heat-insulating material, comprising grinding the silicate-clay to a specific surface of 2500 cm²/g, mixing it with a modifier, a strengthening additive - portland cement, basalt microfibre and mixing water, placing the resulting mixture in a mould, heat treatment with microwave currents for 15 minutes at a temperature of 300°C, a water repellent agent 136-41 is used as a modifier in the following ratio components of the mixture, wt %: the said silicate block 65, hydrophobic agent 136-41 0.08, Portland cement 13, basalt microfiber 0.92, mixing water 21.

EFFECT: improvement of physical and mechanical properties.
