Aluminate Cement

Alumina cement is an inorganic material that forms a dense texture after it reacts with water. It has excellent refractoriness, quick hardening, and resistance to chemical attacks. High alumina cement is widely used for the production of high quality refractory castables and other special products.

Monolithic refractory technology has grown to include calcium aluminate cements in many products with enhanced properties and installation systems, such as low cement, ultra-low cement, low moisture, high density, self-flowing, pump-able and formless (shotcrete) castables.

We also have Calcium Aluminate Clinker, Calcium Aluminate Cement. Contact KT refractories for high purity Aluminate Cement, or other refractory raw material because we save you time and money!
