Application:
1.It is a kind of aluminate cement wrought material based upon calcium aluminate, it is called Aluminate cement when it has been finegrinded to hydraulicity cementing material, its code is CA. When the cement has a grinded Al2O3 content of above 68%, it can be added with appropriate amount of α-Al2O3 powder as requirement.
2.Aluminate cement can be classified into four kinds by Al2O3 content:
CA-50, CA-50/A600, CA-50/A700, CA-50/A900, CA-70,CA-80
3.It can be used to formulate unshape refractory material; expansive cement, self-stressing cement, addition material of chemical construction material and projects with special requirements.
