.Aluminate Cement CA50-G9Character & Uses
| Brand | CA50-G9 | Mineral Phases | Main Phases | CA |
| Type | High strength | Secondary Phases | CA2, CT, C2AS | |
| Character & Uses 1. Main phase isCA. 2. Rapid hardening and early strength. 3. Better settingtime due to suitable mineral compositon. Initial setting time isprolonged and final setting time is shortened. The shortenedinterval provides enough working time and reduces the maintainingtime. 4. Its capacity and strength are more advancedthan other aluminate cements. 5. Used for bind of refractorymaterial and building mortar coagulant. 6. It is used abroadfor ready-made constructional structures to speed up constructionin order to raise the working effciency. Shorten the time limit fora project, save time and money. 7. It can be used inrush repairs, , rush constrction, sulphate-resistant projects, theprojects in winter and so on. | ||||
