专利汇可以提供High strength refractory concrete专利检索，专利查询，专利分析的服务。并且A refractory concrete of improved strength made from calciumaluminate cement, a refractory aggregate of ferro-chromium slag, and as an additive, powdered boron phosphate. According to the method of the invention the graded slag is admixed with the phosphate additive and aluminate cement to form a concrete grog, which is subsequently fired in air to temperatures of 1,000*C or higher. A ceramic-type bond is thereby formed, transforming the concrete rapidly into a dense refractory body.，下面是High strength refractory concrete专利的具体信息内容。

权利要求

2. The composition of claim 1 wherein said slag comprises by weight percent 25-40% MgO; 20-50% SiO2, and 10-40% Al2O3.

3. The composition of claim 1 wherein the cement to aggregate ratio is approximately 1:4, and the water to cement ratio approximately 0.6.

4. A composition in accordance with claim 1, further including as a high temperature flux, less than 5 parts per hundred by weight of the solid components of boron phosphate.

5. A method of forming a high strength refractory concrete comprising: admixing graded ferro-chromium slag and a high temperature calcium-aluminate cement with water; forming a desired concrete structure from the aqueous admixture; and thereupon firing said concrete structure to at least 1,000*C in air.
