透水混凝土是一种绿色化新型材料,在其发挥其自渗水功能的同时不可避免的一些杂质会下渗到透水混凝土中,影响透水功能的正常使用。为更好地评价透水混凝土渗透衰减性能,提出渗透衰减率的概念,通过设计多组不同骨料粒径配合比的试验,进行透水系数测定试验,分析评价渗透衰减率,最终得出透水混凝土渗透衰减与骨料粒径、比例、分布之间的关系。
透水混凝土是一種綠色化新型材料,在其髮揮其自滲水功能的同時不可避免的一些雜質會下滲到透水混凝土中,影響透水功能的正常使用。為更好地評價透水混凝土滲透衰減性能,提齣滲透衰減率的概唸,通過設計多組不同骨料粒徑配閤比的試驗,進行透水繫數測定試驗,分析評價滲透衰減率,最終得齣透水混凝土滲透衰減與骨料粒徑、比例、分佈之間的關繫。

Pervious concrete is the green new material from water seepage in their play to their capabilities ,while some of the inevitable impurities infiltration into pervious concrete,permeable features affect the normal use.To better evaluate the performance of pervious con-crete permeability decay,the decay rate of penetration of the concept put forward by designing multiple different aggregate size ratio test , conducted permeability coefficient measurement test,analysis and evaluation of permeability decay rate,and ultimately come to pervious concrete infiltration attenuation and between aggregate size and scale.
