摘　　要：试验研究了粗骨料品种、粗骨料粒径、胶骨比等对透水混凝土力学性能和透水性能的影响,结果表明:采用天然骨料配制的透水混凝土的各项性能均优于采用再生骨料配制的透水混凝土;对于同一来源的粗骨料,骨料粒径越大,配制的透水混凝土透水性能越好,力学性能则略有降低;相同品质和粒径的再生骨料配制的透水混凝土,随胶骨比增加,混凝土透水性能逐渐降低,力学性能却呈增加趋势。The Paper studied the effects of coarse aggregate varieties, the particle size of coarse aggregates and cement aggregate ratios on the mechanical properties and permeability of pervious concrete. The results showed that the pervious concrete prepared by natural aggregates exhibited better properties than that prepared by recycled aggregates. For coarse aggregate of the same origin, the concrete prepared by aggregates with larger particle size showed better permeability, while the mechanical properties were slightly decreased. The permeability of pervious concrete prepared by recycled aggregate with the same quality and particle size reduced gradually while the mechanical properties increased when the permeability of concrete decreases gradually.
