  • Cementitious composite material with silicon carbide aggregate
    Patent number: 4666520
    Abstract: An improvement over the cementitious composite material described in U.S. Pat. No. 4,482,385 consists in replacing the stainless steel particles with graded silicon carbide particles. The resulting material has a lower coefficient of thermal expansion, a greater thermal conductivity and an increased surface abrasion resistance as compared to the material described in the patent and is a lighter weight material. These properties enhance its applicability to certain uses.
