Description for High Alumina Cement

High Alumina Cement uses bauxite and lime as the raw materials, which is a kind of hydraulic binders with aluminate as the main mineral composition that through calcining and grinding fine according to certain proportion. Its professional title is Aluminate Cement.

Rongsheng as one of professional high alumina cement suppliers manufactures all kind of refractory cement for various furnaces and kilns building to resist sulfate attack.

Properties of High Alumina Cement

Early strength characteristics: Its early strength increase rate is far more than rapid hardening portland cement, high alumina cement is suitable for emergency repair engineering. Take restrictions on the use in structure engineering to prevent from the long-term strength reducing.

Larger heat of hydration: Early cement hardening heat release is larger. Compared with Portland cement at same grade, just a day can release 70 ~ 80% of the total heat of hydration. Due to the several kinds of heat release, high alumina refractory cement is suitable for low temperature curing of concrete engineering.

Strong resistance to sulfate attack: hydration process generates aluminium hydroxide gel to form a protective film instead of non-precipitating free alternating current calcium hydroxide. Latterly in the crystal transformation in the process of the erosion resistance will decrease.

Good high temperature resistance: High alumina refractory cement can be used as heat resistant concrete cementitious materials to be configured to heat resistant concrete.

Application of High Alumina Cement

High alumina cement is mainly used to configure refractory castable such as high alumina low cement castable which can build or repair furnace or kiln for heat insulation or high temperature erosion.

 

 

Calcium aluminate cement has high temperature resistance performance,can keep high strength under higher temperature,and the high temperature property will be improved along with increase of the CA2 content .As bonding agent,with different aggregate,we can make refractory castables with 1400°c refractoriness.
