Fused Calcium Aluminate Cements CA80 are calcined by natural high grade bauxite and limestone as selected raw material. The main phase of this series is CA and CA2, α Al2O3 which mainly formed the clinker. After grinded to the best particle size distribution, the cements will meet the demand of the most critical customers.
★ High early strength, fast setting and hardening.
★ The high heat of hydration, the hydration heat concentration
★ The high heat of hydration with exothermic concentration
★ The frost resistance is good, normal hardening can also in the lower temperature environment

Calcium aluminate (CA) cements are similar to the more familiar Portland cements in that they both require water for hydration, they both form concretes that set in about the same time, and they both require similar mix designs and placing techniques. There are, however, important differences between the two cements. First, Portland cements are made by reacting limestone and clay to produce calcium silicates, while calcium aluminate cements (also called high-alumina cements) are made by reacting a lime-containing material with an aluminous material to produce calcium aluminates.
