基于透水混凝土渗透衰减规律的骨料响应分析

Response analysis of aggregate based on pervious concrete penetration attenuation law

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Expert Desigh8.0设计软件并采用混料设计的试验方法,对透水混凝土的骨料配合比进行试验分析,建立渗透衰减同骨料配合比的响应面方程,为混凝土骨料配合比的设计提供一定的参考。

Pervious concrete is a green new material in it to play its self seepage function while some unavoidable impurities infiltration into the permeable concrete,affect the normal use of permeable functions.To better evaluate the performance of pervious concrete per-meability decay,the decay rate of penetration of the concept put forward by the Expert Desigh8.0 design software and the use of test methods mixing design of pervious concrete aggregate ratio test analysis,penetration attenuation with aggregate ratio of response surface equation,to provide a reference for the design of concrete aggregate ratio.
