Product Details

Product Description

High Alumina Cement (previously called bauxite cement) is a kind of grinding hydraulic cementing materials with clinker about 50% alumina content and has calcium aluminate as the main material, which is also called refractory cement, which can be made to low cement high alumina castable to build or repair all kinds of furnace and kilns for thermal insulation or acid erosion resistance with high strength. The raw materials of calcium aluminate cement CA-70/80 are high purity calcium materials and high pure alumina. The raw materials should be mixed according to suitable ratio. The raw material should be burned to partly fuse. After cooling, α-Al2O3 powder added into clinker, then ground to cement. The content of Al2O3 is usually controlled within 68% to 72%. The principal compounds of it are CA and CA2.

Features and Advantages:

1. High refractoriness, high refractoriness under load.

2. High density, low porosity.

3. Good slag resistance and corrosion resistance.

4. High strength and wear resistance.

5. Good resistance to flake performance.

6. Good thermal shock stability.

7. Scouring resistance 8. Good hot strength.

Applications:

In construction concretes, rapid strength development is achieved, even at low temperatures.

In construction concretes, high chemical resistance is possible.

In refractory concretes, strength is maintained at high temperatures.

As a component in blended cement formulations, various properties such as ultra-rapid strength development and controlled expansion can be obtained.
