Aluminate Cement CA65Aluminate Cement CA50-NCharacter & Uses
| Name | Type | Main Phase | Seconday phase | Character & Uses |
| CA65H | High strength | CA2, C2A2S, CA | (CA6), CT, α. Al2O3 | 1. bond of high temperature refractory 2. longer setiing time3. strength tested by 3 days and 28 days 4. high early andrapid strength, and higher strength of later term, better stabilityin air. 5. refractoy castables used between 1300 to1600°C can be confected according to different aggregateproperties. 6. excellent result in the projest of flow-directingpath of satellite-launching pads. No repairs are needed after tensof launchings. |
| CA65P | Pure calcium Aluminate | CA, CA2 | α.Al2O3 | 1. belong to pure almuniate cement 2. no additive 3. high earlyand rapid strength 4. suitable to confect all kinds ofrefractory castables and low cement refractory castables. |
