    摘要:

    在透水混凝土配合比相同的条件下采用粒径范围在2~5mm和5~10mm的河卵石,等份分层浇筑形成的透水混凝土试块与该两种粒径范围分别单一浇筑成型试块的性能进行对比分析。试验发现:粗骨料分层的透水混凝土试块有效孔隙率、抗压强度值和透水系数均介于骨料不分层所形成试块的有效孔隙率、抗压强度和透水性系数之间;同时分析了骨料分层的透水混凝土有过滤、有效预防“持久污染”、行走时有舒适感的作用在一般的工程应用上所体现的优势,为以后工程应用提供参考。

    Abstract:

    The permeable concrete that was stratified pouring by using pebble of particle size in 2~5mm and 5~10mm were analyzed with the permeable concrete of single pouring of the two particle size range pebble under the same condition of mix proportion. The results show that the effective porosity、compressive strength and permeable coefficients of aggregate layered permeable concrete is between with the effective porosity、compressive strength and permeable coefficients of the two kinds of permeable concrete of single poured. At the same time,it is analyzed the advantages in engineering application that is the filter、effectively prevent “persistent pollution” and the effect of comfort when person worked in a normal,to provide reference for later engineering application.
