| 摘要: |
| 用粉煤灰、氟石膏和水泥配制成了一种新型的水硬性胶凝材料——粉煤灰-氟石膏-水泥复合胶凝材料.其中,水泥掺量可以少于15%(质量分数,下同),而粉煤灰和氟石膏掺量可多于85%.试验结果表明:尽管氟石膏的掺量很大,但该胶凝材料具有良好的体积安定性;这种胶凝材料不仅成本低廉,而且是一种环保型材料,值得推广应用. |

| Abstract: |
| Fly ash,fluorogypsum and cement were used to make a new kind of hydraulic binder.It is shown that the fraction of cement in the binder can be less than 15%, and the franction of fly ash and fluorogypsum can be more than 85%.The binder has good soundness in spite of its high use level of fluorogypsum.The binder is a material which is beneficial to environment,low-cost and worthy to be widely used. |
| Key words: fly ash,fluorogypsum,cement,hydraulic binder,soundness |
