Raw material and fuel are well selected in order to reduce impurities. After calcined in rotary kiln with perfect temperature control, the strength of CA50-G9 is nearly doubled of that of CA50-G5, that is, the compressive strength (3d) of CA50-G9 reaches 80-95Mpa or even higher. The quality is as good as that of overseas products or even better while price is much lower.

Character & uses:
1. Main phase is CA.
2. Rapid hardening and early strength.
3. Better setting time due to suitable mineral composition. Initial setting time is prolonged and final setting time is shortened. The shortened interval provides enough working time and reduces the maintaining time.
4. Its character and strength are more advanced than other aluminate cements.
5. Used for bind of refractory material and building mortar coagulant.
6. It is used abroad for ready-made constructional structures to speed up construction in order to raise the working efficiency, shorten the time limit for a project, save time and money.
7. It can be used in rush repairs, rush construction, sulphate-resistant projects and projects in winter etc.
We also provide the other varieties such as: (CA50-G6) Aluminate Cement (resist a high temperature at which a relative high strength still remains); (CA50-G7) Aluminate Cement. The alumina content is 50---59% in the CA50 series.
