Character and uses:
1. Bond of high temperature refractory.
2. Longer setting time.
3. Strength tested by 3 days and 28 days.
4. High and rapid strength in early time; higher strength in latter time.
5. Better stability in air.
6. Refractory castables used between 1300 to 1600Celsius degree can be confected according to different aggregate properties.
7. Excellent result in the project of flow---directing path of satellite---launching pads. No repairs are needed after tens of launchings.
