| 摘要: |
| 研究得出了使粉煤灰-氟石膏-水泥复合胶凝材料(FFC胶凝材料)强度达到较大值的氟石膏、粉煤灰和水泥之间的较佳用量比例关系.结果表明:随氟石膏用量的增加,FFC胶凝材料的干缩变小;FFC胶凝材料具有良好的体积安定性;当水泥和粉煤灰用量相等时,FFC胶凝材料的强度大于粉煤灰-磷石膏-水泥复合胶凝材料(FPC胶凝材料)的强度. |

| Abstract: |
| The optimal proportion of blending content among fluorogypsum,fly ash and cement of fly ash-fluorogypsum-cement composite binder(FFC binder) was known through the study.The experimental results show that FFC binder's dry shrinkage will decrease with the increase of the blending content of fluorogypsum,and FFC binder's soundness is good.The strength of fly ash-phosphogypsum-cement composite binder(FPC binder) is lower than that of FFC binder if the blending content of cement and fly ash in them is equal to each other. |
