Calcium Aluminate Cement

It features fast setting, high early strength, excellent high-temperature resistance and good chemical stability.

Product Description

Calcium Aluminate Cement is made from high-quality Bauxite and Limestone through high-temperature calcination, with calcium aluminate (CA, CA₂) as the main mineral phase. It features fast setting, high early strength, excellent high-temperature resistance and good chemical stability. It has excellent compatibility with various refractory aggregates, making it an ideal binder for high-temperature refractory castables, plastics and gunning mixes. It is widely used in industrial furnace linings in metallurgy, building materials, petrochemical and other industries.
