| 摘 要： | 本文以再生骨料透水混凝土为研究对象,分析了再生骨料粒径的大小对透水混凝土强度和空隙率的影响,在保证混凝土取得较高强度和孔隙率的基础上确定了最佳的再生骨料粒径。同时,还尝试性地研究了体积砂率对再生骨料透水混凝土强度的影响,并以试验数据为基础确定了达到强度峰值时的最佳体积砂率值。

| Abstract: | The chapter is aimed at the research of the recycled aggregate porous concrete. It analyzed the influence of recycled aggregate particle size on the strength and porosity of pervious concrete. The best recycled aggregate particle size was determined on the premise that the concrete made in ensuring high strength and porosity. Also, we have tried to study the effects of the volume percentage of sand on strength of recycled aggregate pervious concrete. And on the basis of experiments, the best value of the volume percentage of sand was determined, when strength of recycled aggregate pervious concrete reached the peak. |
