What is the high alumina refractory cement?

1.high alumina refractory cement is also called bauxite cement,high alumina cement,aluminate cement and calcium aluminate cement.

2.high aluminarefractory cement is made by high alumina bauxite and limestone materials.

3.high alumina refractory cement is usually used for making refractory concrete or refractory castable.
