Character & uses:
1. The main phase is CA, content approx. 70-80%.
2. To have long initial setting time and long constructing time.
3. The interval between initial setting time and final setting time is short, and it is availed to improve the strength and to remove the mould.
4. The good flowability could improve the work performance of concrete effectively.
5. Impurity content is lower, the strength falls less in middle temperature.
6. A perfect bond for confecting high-strength and good-flowability rapid hardening refractory castable.
7. The bond for confecting gunning material or castables with resistance to abrasion, vibration and high temperature.
8. Confecting self-leveling screed.
9. Confecting rapid hardening mortar, ceramic tile paste agent and project stagnant water material.
