摘要
在深圳市大力建设海绵城市的背景下,为助力海绵城市的发展,研究了透水混凝土性能的几个影响因素.通过文献调研及试验,归纳总结出集料粒径、配合比、集胶比、减水剂、硅灰及可分散乳胶粉对透水混凝土抗压强度和透水性能的影响,并阐述其作用机理,为透水混凝土配合比设计和材料选择等方面提供一定的借鉴.
Abstract
In the context of vigorous construction of sponge city in Shenzhen,in order to help the development of sponge city,several influencing factors of permeable concrete performance are studied.Through literature investigation and experiments,the effects of aggregate particle diameter,mix ratio,aggregate/binder ratio,water reducing agent,silica fume and dispersible latex powder on the compressive strength and permeability performance of permeable concrete are summarized,and their mechanism of action is elaborated,which provide some reference for the design of permeable concrete mix ratio and material selection.
