Abstract: In order to solve the efflorescence of castable refractory, experiments were conducted with different raw materials and alumina cement. The result shows that some raw materials can promote efflorescence of castable refractory. Choosing raw materials reasonably and taking some actions can reduce efflorescence.

Key words: efflorescence, alumina cement
