Aluminate Cement CA50-FusedCharacter & Uses
| Name | CA50-Fused | Mineral Phases | Main Phases | CA |
| Type | High early strength | Secondary Phases | C2AS, C12A7 | |
| Character & Uses 1. Main phase CA contentis approx. 70%-80%. 2.Has long inital setting time and longwork time. 3. The interval of initial setting time and finalsetting time is short, it is availade to improve the strength andto remove the mould. 4. The good flowability could improve the workperformace of concrete effectively. 5.Impurity content is lower, the strength of middle temperature downextent lesser. 6. A perfect bond forfomulating rapid hardening high strength and food flowabilityrefractory castable. 7. The bond for formilatinggunning material with resistance to elevated temperature. 8.Formilating for self-flowing ground materials. 9.Formulating for rapid hardening mortar, ceremic tile paste agent,stop water project materials. | ||||
