Character & uses:
1. Without free calcium oxide.
2. Main phase is CA.
3. Used as coagulant in Portland cement to accelerate hardening and to shorten time for a project.
4. Used to confect self-leveling screed. (Self-leveling Screed is composed of cement-based cementation material, aggregate, filling and additives. It has fluidity under the state of mixing newly. Or spread out complementarily and it can flow and make screed by itself.)
5. Used to make quickly drying and quickly hardening ground.
6. Used as ceramic adhesive.
7. Used for quick hardening and high strength mortar.
