Aluminate Cement CA50-NCharacter & Uses
| Brand | CA50-N | Mineral Phases | Main Phases | CA |
| Type | Super-early-strength | Secondary Phases | CA2, CT | |
| Character & Uses 1. The settingtime is normal. Its quick hydrating and hardening property makeshigh strength in short time. Its strength can reach 30 Mpa in 6hours after hydrating, and 50 Mpa in 24 hours. 2. It is an ideal binder for rapid hardening and high strength low cementcas-tables. 3. It is also suitable for high alumina orfire-claylow-cement refractor castables unsed under 1450 °C. 4. Its price is much lower than pure calium aluminate so that itcan makes the cost lower. 5. It needs moisture proofprotection and can be used at least within six months if it isstored under dry condition. | ||||
