摘　　要：以C20透水混凝土为设计基准,水灰比为0.3,橡胶颗粒体积掺量为0、3%、6%、9%和再生骨料体积取代率为0、50%、100%的13组试验配合比,对透水混凝土进行透水性能和力学性能进行试验,并利用CT扫描技术观察透水混凝土的细观结构,研究再生骨料和橡胶颗粒对透水混凝土性能的影响,获取橡胶颗粒和再生骨料与透水混凝土基本性能的关系。试验结果表明:掺加橡胶颗粒和再生骨料均会降低透水混凝土的基本力学性能;随橡胶颗粒掺量的增加,透水混凝土的透水系数和孔隙率逐渐降低。It designed 13 mix proportions on C20 pervious concrete with the water cement ratio of 0.3 with the rubber particles different replacements of 0、3%、6%、9% and the recycled aggregate with different replacement of 0、50%、100% to put permeability and mechanical property on trial.Meanwhile,it detected the micro structureof pervious concrete through the CT scanning technique,analyzed the mechanism influenced by the rubber particles on the performance,the relationship between the rubber particles,recycled aggregates and the performances of pervious concrete based on the data regression were obtained.The results showed that both recycled aggregate and rubber particle can reduce the basic mechanical properties of concrete,the more rubber particles,the less continuous porosity and permeability coefficient.
