Product Description
Polar Bear CSA
Calcium Sulfoaluminate Cement(CSA Cement) and CSA powder.
1. Calcium Sulfoaluminate Cement (CSA Cement, CSA Binder, R-SAC)
Also named Calcium Sulphoalumate Cement.
High-strength Grade: 42.5, 52.5, 62.5, 72.5;
Super-high-strength Grade: 825, 925, 1025.
CSA Cement has high early strength. Its performance of fast hardening, impermeability, frost and corrosion resistance is more excellent than those of Portland Cement. It has a remarkable effect on restraining alkali aggregate reaction. Its alkali is lower. pH value is only 10.5-11. CSA Cement is special fit for making GRC products, for example GRC composite exterior panel, GRC lightweight panel, GRC lightweight hollow core panel, GRC exterior wall with insulation panel, etc. Moreover, it is widely used in making concrete with performance of impermeability, frost and sulfates corrosion resistance, precast component, pole, pipe and manmade marble goods.
2. Calcium Sulfoalumnate(CSA powder):
It is a kind of mineral with high early strength. It is main composition of rapid-setting cement, expansive cement, self-stressing cement. It is also used as accelerating admixture, rapid setting admixture, bloating agent for Portland Cement.
