灰骨比对绿色生态混凝土抗压强度及空隙率的影响分析

绿色生态混凝土是一种以再生骨料、工业废料为主要原材料配制的植生型混凝土,其不仅有利于节省资源、能源,而且还能平衡生态环境。其性能影响因素可归纳为:材料组成、制备方法、养生条件及实验条件等四个方面。本文仅研究材料组成方面中的灰骨比对绿色生态混凝土抗压强度及空隙率的影响。试验结果表明:采用不同粒级的再生骨料、水泥浆水灰比配制的绿色生态混凝土,其抗压强度均随着灰骨比的减小而减小,全孔隙率及透水系数随着灰骨比的减小而增大。

Analysis of the effect on cement-aggregate ration to green ecological concrete＇s compressive strength and porosity

Green ecological concrete is a kind of restoring vegetation concrete confected by recycled aggregate and industrial waste which were the major primary materials.It was not only helpful to saving resources and energy,but also balancing ecological environment.Its properties influencing factors could be concluded to material composition,preparation method,curing condition,experimental conditions etc four aspects.This article only studied on the effect on cement-aggregate ration which was grouped into material composition aspect to green ecological concrete＇s compressive strength and porosity.The results showed that green ecological concrete＇s compressive strength was decreased with cement-aggregate ration＇s decrease when it was confected by different particle size or cement slurry water-cement ration,However,it＇s whole porosity and water-permeable coefficient were increased with cement-aggregate ration＇s decrease.
