摘　　要：系统研究了再生骨料、石灰石骨料、卵石骨料以及矿渣微粉掺量对透水混凝土孔隙率、耐磨性能的影响,并考虑了骨胶比的作用。采用冲击磨损及表面磨损试验以混凝土质量损失率来对比评价混凝土耐磨性能。结果表明:骨胶比对透水混凝土孔隙率影响最大,骨胶比的大小基本与混凝土孔隙率成正比;粗骨料类型对于混凝土冲击磨损性能有很大影响,卵石骨料混凝土冲击磨损性能最差,但表面耐磨性能最好,再生骨料的使用对透水混凝土耐磨性能并没有产生不利影响;随着骨胶比的增加,混凝土表面耐磨性能变差;增加矿渣微粉含量并没有对混凝土表面质量损失造成不利影响。矿渣微粉掺量增加至30%没有降低混凝土耐磨性,结合数据分析,混凝土表面磨损质量损失与冲击磨损质量损失存在一种线性关系。This paper systematically studied the influence of the content of recycled aggregate, limestone aggregate, pebble aggregate and slag powder on porosity and wear resistance of the permeable concrete, and considered the effect of bone glue ratio. The wear resistance of concrete was evaluated by impact wear and surface wear test. The results showed that the ratio of bone glue had the greatest influence on the porosity of permeable concrete, and the size of bone glue was basically proportional to the porosity of concrete. The coarse aggregate type had a great influence on the impact wear performance of concrete, and the impact wear performance of pebble aggregate concrete was the worst, but its surface abrasion resistance was the best. The use of recycled aggregate had no adverse effect on wear resistance of permeable concrete. With the increase of bone glue ratio, the wear resistance of concrete surface was worse, and with the increase of slag powder, it had no adverse effect on loss of concrete surface quality. The slag powder content increased to 30%did not reduce the wear resistance of concrete. Combined with data analysis, there must be a linear relationship between concrete surface wear quality loss and impact wear quality loss.
