摘要
对掺粉煤灰自密实混凝土在振捣与不振捣两种情况下,试块的抗压强度和劈拉强度进行了对比,从水灰比、砂率、粉煤灰三方面探讨了影响强度比的因素,重点探讨了粉煤灰对强度比的影响,并对试验结果进行了总结。
Under the two circumstances of vibration and non-vibration, the authors compares and contracts compressive strength and split strength of PFA dense concrete, discusses the factors influencing strength ratio from water/cement ratio, sand content and PFA content. This paper mainly discusses the influence of PFA on strength ratio and summarizes the testing result.
