COMPOSITION FOR PRODUCING POLYSTYRENE CONCRETE, METHOD OF ITS PRODUCTION AND MONOLITHIC BLOCK Russian patent published in 2021 - IPC C04B38/08 C04B24/34 C04B22/08 C04B16/08 B28B1/08 C04B111/20 E04C1/00 

FIELD: building materials.

SUBSTANCE: invention relates to the production of porous building materials, in particular lightweight concrete. The specified technical result is achieved due to the fact that the composition for the manufacture of expanded polystyrene concrete includes polystyrene granules, water, cement grade D0 (M500), sand, characterized in that it additionally contains an aqueous solution of sodium silicate in a ratio of 1:10, as well as wood resin saponified in the form of a 10% aqueous solution. Also described is a method for producing expanded polystyrene concrete and a monolithic block made in this way.

EFFECT: reducing material consumption, reducing the time of construction and finishing work, improving sound insulation, eliminating the need to use additional heaters while maintaining thermal conductivity resistance, reducing moisture absorption, increasing concrete strength and resistance to dynamic loads.
