| 摘 要： | 结合广西百色水利枢纽工程拟用材料特性，经长龄期试验，就粉煤灰掺量、品种的变化对碾压混凝土（RCC）的净浆性能、胶砂强度性能、脆性性质、水化热性能、胶砂干缩性能及RCC凝结时间的影响进行分析，并得出粉煤灰与胶砂性能、胶硝性能与龄期的相关关系，成果为碾压混凝土工程使用粉煤灰提供重要参考依据。

| Abstract: | s: Combining the characteristics of materials planned to be used in Baise project, the influences of different replacement levels and brands of flyash on the properties of neat cement grout, strength of cement mortar, brittleness, cement hydration heat, drying shrinkage of cement mortar and the set time of RCC are analyzed by way of long term experiments, based on which the corelations between flyash and properties of RCC cement mortar, between properties of RCC cement mortar and age are concluded, providing important reference basis for using flyash in RCC project. |
