High Alumina Cement ( CA-50-A600, A700, A900)
Aluminate cement is produced by preparing raw meal consisting of applicable bauxite and limestone, calcining the raw meal in rotary klin and grinding the clinker, which contains Al2O350-59% . It was called bauxite cement for a time and also called " refractory cement" based on its main usage. The name " aluminate cement" is specified by the national standard now.
