Description
CSA cement is one kind of ettringite cements with high initial strength, fast hardening performance, high impermeability, frost and corrosion resistance, which is much better than those of ordinary Portland cement. It was first developed in China in the 1970s,calcium sulfoaluminate cements belong to a class of specialty rapid hardening cements. The primary advantage of making concrete with CSA cement instead of Portland cement is that you can develop the compressive strength within 24 hours, which a strength normally takes 28 days to achieve with conventional Portland cement.
Advantages
1.High early and final strength
2.Rapid hardening and fast setting time
3.High froze-resistance
4.High impermeability
5.Anti-carbonation
6.Corrosion-resistance
7.Green cement, use less energy and produce less CO2
8.Etc.
