SILICON-CARBIDE CONCRETE Russian patent published in 2005 - IPC

FIELD: refractory industry; manufacture of monolithic linings.

SUBSTANCE: proposed silicon-carbide concrete contains the following components, mass-%: plasticizing agent, 0.3-0.5; microsilica, 2.0-5.0; high-alumina cement, 7.0-10.0; the remainder being silicon carbide. Concrete may additionally contain high-alumina component at content of Al₂O₃ no less than 95 mass-% in the amount of 5-15 mass-%, for example in form of synthetic corundum of fraction lesser than 50 mcm or dust from electric filters of calcination furnaces in alumina production process.

EFFECT: enhanced strength of concrete at 600-1000°C; enhanced resistance to oxidation.
