Description features:CemenOWD? high alumina cement is produced by preparing raw material consisting of applicable bauxite and limestone, burning the raw meaterial and grinding into cement
The high alumina 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 alumina)used,the refractory concrete made of the cement can be used below 1400¡ãC. Although the early strenth of high alumina cement develops rapidly,its later strength decreases. The rates of crystabls conversion and strength reduction relates to atmospheric temperature and humidity. In the saturated steam at 35¡ãC, the conversion is complete in 28d and the strength decreases to the minimum, in the dry air below 20¡ãC, the conversion is very slow. So the HAC is not suited to use in buiding engineerings. If it is used in construction, matters needing ttention given in the appendix GB201 must be followed . In order make use of strong points of HAC and overcome its weak point, cement scientists in the world have developed various modified HAC and overcome its weak point, cement scientists in the world have developed various modified HAC series: self-stressing cement, expansive cement, impermeable non-shrinkage cement,rapid hardening high strength aluminate cement. Special rapid hardening setting-controlled aluninate cement and so on. These aluminate cements with special properties are used in rush repairs,quick construction antipermeability, leakage stopping , resistance to sulfate attack, winter constructions etc.We can supply some derivative products of aluninate cement series according to requirements of special engineerin
