| 摘 要： | 研究了石粉代替部分粉煤灰对碾压混凝土和易性、抗压强度、劈拉强度、极限拉伸值等力学性能的影响，并比较了0、50％两种取代率的碾压混凝土凝结时间、绝热温升、抗剪强度、抗渗、抗冻等性能。试验结果表明，石粉替代部分粉煤灰对碾压混凝土的和易性，抗渗、抗冻性能影响较小，混凝土的凝结时间变短，绝热温升降低，但碾压混凝土的力学性能随石粉掺量的增加而减小。

| Abstract: | The influence of limestone powder replacing partial fly ash on RCC performance such as workability, compressive strength, splitting strength, ultimate tension value was studied. Setting time, adiabatic temperature rise, shear strength, permeability and frost resistance performance of RCC of two kinds of limestone powder content were compared. The test results showed that the influence of limestone powder replacing partial fly ash on workability, permeability and the frost resistance of RCC was slight, the setting time of RCC shortened and adiabatic temperature rise reduced, but the mechanics performance of RCC reduced with limestone powder content increasing. |
