摘　　要：为提高水工建筑物的耐久性,水工建筑物中通常采用抗冲磨混凝土。前人研究发现,HF粉煤灰混凝土试块后期抗压、抗冲磨强度明显提高[1]。在前人研究的基础上,分别研究了不同粉煤灰掺量与不同水胶比对HF粉煤灰混凝土抗冲磨性能的影响。试验结果表明:粉煤灰掺量为25%的混凝土试块比粉煤灰掺量为20%的混凝土试块的磨损率小;而且,水胶比越小,混凝土试块的磨损率越大,抗压强度越大。To improve the durability of hydraulic structures, hydraulic structure was often used impact mill concrete.Previous research found that the HF fly ash concrete block later compressive,impact grinding strength had obviously improved [1].On the basis of previous studies,respectively studied on the properties of grinding with the different fly ash content and different water cement ratio.The test results showed that ：when the fly ash content was 25%, the wear rate of the concrete block was smaller than the one with 20% fly content.Moreover, when the water-binder ratio smaller, the concrete block wear rate was much larger and the compressive strength was much greater.
