ETHYNOL PERLITE CONCRETE Russian patent published in 2014 - IPC C04B38/08 C04B26/12 

FIELD: chemistry.

SUBSTANCE: invention relates to construction materials, in particular to manufacturing products from ethynol perlite concrete, applied for heat insulation of heat pipelines of heat networks and for manufacturing heat-insulated pipes of full operational readiness with monolithic thermohydroinsulating protection. Ethynol perlite concrete, obtained from composition, which contains perlite gravel with filling agent from inert materials; as such used are dust-like asbestos in form of powder in amount 0.2 ppm, expanded clay aggregate dust in amount 0.2 ppm, and fly ash of thermal power stations in amount 0.2 ppm, and composite cement in form of ethynol enamel based on ethynol varnish in amount 1 ppm and plasticiser, represented by latex SKS-65 in amount 0.1 ppm, and as accelerator of composition polymerisation used is intensive ultraviolet radiation.

EFFECT: increased quality of ethyl perlite concrete due to reduction of water absorption, heat conductivity coefficient, increase of water resistance and acceleration of hardening.
