摘要
为了明晰再生骨料掺率对再生骨料透水混凝土抗压强度及孔隙率的影响,设计了6种再生骨料掺率方案(0%、10%、20%、30%、50%、100%),进行研究,并对再生骨料掺率与孔隙率之间进行线性拟合,试验结果表明,再生骨料透水混凝土抗压强度与孔隙率能够满足要求,当再生骨料掺率为20%时,再生骨料透水混凝土的抗压强度最大,为17.7MPa。
In order to clarify the effect of the proportion of recycled aggregate on the compressive strength and water permeability of pervious recycled aggregate concrete,six mixing rate(0%,10%,20%,30%,50%and100%)of recycled aggregate were designed for study,and the linear fitting between recycled aggregate mixing rate and porosity,compressive strength and water permeability was performed,test results show that the compressive strength and water permeability of pervious recycled aggregate concrete can meet the requirements,and when the proportion of recycled aggregate is20%,the compressive strength of pervious recycled aggregate concrete is the largest,is17.7MPa.
