High-alumina Cement of Refractory Products with Low Content of FE2O3 For Rush Construction

1.Products description

High-alumina cement is a rapid-hardening cement made by fusing at 1,500° to 1,600° C (2,730° to 2,910° F) a mixture of

bauxite and limestone in a reverberatory or electric furnace or in a rotary kiln. It also can be made by sintering at about 1,250° C (2,280° F).

High aluminum cement is produced by preparing raw material consisting of applicable bauxite and limestone, burning the raw

meaterial and grinding into cement.

The high aluminum cement can resist a high temperature at which a relative high temperature at which a relative high strength

still remains.Its refractoriness increases with the content of CA2. Therefore it is suitable to make refractory concrete as a binder.

Depending on the refractory aggregate(fireclay,high aluminum)used,the refractory concrete made of the cement can be used

below 1400°C.

We can supply some derivative products of aluminatum cement series according to requirements of special engineerings.
