Aluminate cement is produced by preparing raw meal consisting of applicable bauxite and limestone, calcining the raw meal in rotary kiln and grinding the clinker, which contains Al2O3 50-59%. The aluminate cement can resist a high temperature at which a relative high strength still remains. Its refractoriness increases with the content of CA2. Therefore it is suitable to make refractory concrete as a binder. Depending on the refractory aggregates (firecaly, high alumina) used, the refractory concrete made of the cement can be used below 1400centigrade.
We can supply all kinds of CA50 cement, for example,
CA50-G6 (Al2O3>=50%)
CA50-G7 (Al2O3>=50%)
CA50-N (Al2O3: ~ 55)
CA50-G9 (Al2O3: ~ 55)
CA50-Fused (Al2O3: ~ 55)
If you are interested in such kinds of cement, I will be pleased to tell you the more detailed technical index
