再生骨料透水混凝土的强度和透水性能试验研究

摘要

Recycled aggregate pervious concrete integrates the function of the recycled concrete and permeable concrete advantages,which have important application prospect in the road and landscape architecture engineering.With the double index of strength and permeable coefficient,factors that have influence on the permeable concrete intensity recycled aggregates, including the particle size, size distribution and composition,and water-binder ratio (0.25,0.30,0.35),the adding of mineral admixture proportion (10%, 20%,30%),target porosity (15%,20%,25%),and permeable coefficient,were experimentally studied. The configuration method of recycled aggregate pervious concrete was proposed.Results are useful for permeable concrete proportion design and construction technology of recycled aggregates.%再生骨料透水混凝土集成了再生混凝土和透水混凝土的功能优点，在小区道路和景观工程中有重要应用前景。采用强度和透水系数双指标控制，试验研究了再生骨料的粒径、级配和组成、水胶比（0．25、0．30、0．35）、矿物掺和料及掺加比例（10％、20％、30％）、目标孔隙率（15％、20％、25％）等因素对再生骨料透水混凝土强度和透水系数的影响，给出了再生骨料透水混凝土的配制方法，研究成果对于再生骨料透水混凝土的配比设计及施工技术应用具有工程应用价值。
