Detailed Product Description
An aluminate cement wrought material based upon calcium aluminate;used to projects special requirement.
It is a kind of aluminate cement wrought marerail 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 a-Al2O3 powder as requirement.
Aluminate cement can be classified into four kinds by Al2O3 content:
CA-50,CA-60,CA-70,CA-80
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.
