摘要
研究目标孔隙率、再生骨料替换率、再生骨料粒径及粉煤灰替换率对透水混凝土力学性能的影响,通过试验分析了各因素对透水混凝土的工作性能、抗压强度、抗折强度和透水系数等性能指标的影响.结果表明,再生骨料的掺入在一定程度上降低了透水混凝土的力学性能,但透水性能得到了显著提升.
Abstract
The effects of target porosity,recycled aggregate replacement rate,recycled aggregate particle size and fly ash replacement rate on the mechanical properties of permeable concrete are studied,and the effects of various factors on the workability,compressive strength,flexural strength and permeability coefficient of perme-able concrete are analyzed through experiments.The results show that the incorporation of recycled aggregate reduces the mechanical properties of permeable concrete to a certain extent,but the permeability is significant-ly improved.
