Calcium aluminate cement is a cement with calcium mono aluminate or calcium aluminate as the main mineral component. Other names of calcium aluminate cement are CAC cement, refractory cement, calcium alumina cement and so on.
When making calcium aluminate cement, manufacturers typically use two methods, sintering and fused (electric melting). Sintering of calcium aluminate cement refers to heat the prepared raw materials at high temperature to improve the refractoriness. Fused calcium aluminate cement refers to the use EAC furnace to melt raw materials and results in products with higher purity.
Kerui controls good raw materials and advanced production technology, which brings high-quality refractory cement for sale on the market.
