High Aluminate cements

High alumina cement (bauxite cement) is a hydraulic cementing material with aluminate as the main mineral component, which is prepared by using bauxite and lime as raw materials, prepared in a certain proportion, and calcined and ground. , Also known as aluminate cement.

2. Main usage:

(1) Preparation of unshaped refractory materials.

(2) Preparation of cement for special purposes such as gypsum bauxite expansive cement and self-stressing cement.

(3) Projects with special requirement such as rush construction, rush repair, sulfate erosion resistance and winter construction.
