We make two types of calcium aluminate cement or as they are better called as high alumina cement. “Horizon Refractories” calcium aluminate cements are highly regarded in the refractory and construction industry for being consistent and accurate in quality with all chemical and physical parameters. Our high alumina cement is widely used for:
H-CEM-50 : it is conventional refractory cement with about 50% alumina content.
H-CEM-70 : it is high purity calcium aluminate cement with about 70% alumina content and extremely low impurities. It is used for various critical applications.
