在对柿竹园有色金属矿全尾砂及鲤鱼江发电厂粉煤灰的物理力学性质和化学成分分析的基础上，通过大量试验确定了粉煤灰全尾砂胶结充填中活化剂种类及其最佳掺加量（占粉煤灰的质量分数）为：石灰３０％、石膏２０％、ＣａＣｌ２０５％～１５％。借助硬化体扫描电镜观测结果，揭示了活化剂的作用机理。 Based on the analysis of the physical and mechanical properties and the chemical composition of the fly ash from the non-ferrous metal ore tailings in Shizhuyuan and Liyuejiang Power Plant, the types of activators and their The best dosage (accounting for fly ash mass fraction): lime 3  0%, gypsum 2  0%, CaCl20  5% ~ 1  5%. Scanning electron microscopy observations of the hardened body revealed the mechanism of action of the activator.
