| 摘 要： | 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份分析的基础上,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(占粉媒灰的质量分数)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.

| Abstract: | On the basis of physical, mechanical and chemical characteristics of Shizhuyuan Non-ferrous Metal Mine's crude tailings and Liyjiang Power Plant's flyash, a number of tests were made to determine activators and their percentages suitable to cemented flyash and crude tailing fill. The results obtained are as follows: 0.3% lime, 2.0% plaster and 0.5% ~l.5% CaCl2. Hardenite is observed by SEM to reveal their action mechanism. |

| Keywords: | flyash activator strength of fill |
