生态环境材料 让城市自由呼吸 — 关于透水混凝土用于城市生态道路铺装的探讨 Make the city breathe freely — Discussion about Previous concrete used in Ecological road pavement 张力张林（中美合资南京标美彩石建材有限公司，南京210036 ） 摘要：透水混凝土是一种能减轻环境负担、与自然环境协调共生 能为人类构造舒适生活环境的功能材料， , 既具有透气性、保水性、通气性，容重小并保留混凝土强度高的特点，同时又能满足路用及铺地强度和耐久性 要求的地面铺装。 目前，国内透水性混凝土已经在各个城市广泛应用，其在缓解城市热岛效应、减小地表径 流、补充地下水资源、截留渗透雨水有效遏制城市内涝等方面发挥重要的作用。 本文重点阐述了透水混凝土 的应用在建设现代生态城市中发挥的重要作用。 关键词：透水混凝土；城市；环境；生态建设 Abstract: Previous concrete is a kind of functional materials which can reduce the burden on the environment, symbiotic coordination with the natural environment and construct a comfortable living environment of human, and not only with the features of air permeability, water-holding capacity, aeration, bulk density of small and re- tain the characteristics of high concrete strength,but also meet the road use and the strength and durability re - quirements of the ground pavement.At present, Previous Concrete is widely used in various cities,which plays an important role in easing Urban Heat Island Effect, reducing Surface runoff, addeding groundwater Resources, inter- cepting infiltration of rainwater in order to contain City waterlogging effectively,and so on. This article focuses on the application of pervious concrete in the construction of a modern eco-city played an important role 。 中图分类号： 文献标识码： 文章编号： （ ） TU377 B 1003-8965 2009 03-0047-05 城市生态环境建设是城市的重要基础环节，是 上。 城市发展整体战略中最为重要的内容之一。城市道
