摘 要:基于灰色关联分析法构建以再生骨料透水混凝土抗压强度、劈拉强度、孔隙率、透水系数及质量损失率为评价指标的优选模型,计算得到再生微粉掺量与最优指标集的关联程度。结果表明,0、10%和20%三种再生微粉掺量的灰色关联度较高;掺量为0时,再生骨料透水混凝土的强度最高,10%掺量能够改善其耐磨性能;20%掺量能够显著提高其透水性能。 Abstract: Anoptimalmodelwasestablishedforevaluatingthecompressivestrength,splittingtensilestrength,porosity,permeabilitycoefficientandmasslossrateofrecycledaggregateperviousconcretebasedonthegreyrelationalanalysismethod,andthecorrelationdegreebetweendifferentcontentofrecycledfinepowderandtheoptimalindexsetwascalculated.Theresultsshowthatthegraycorrelationdegreeofthecontentofrecycledfinepowderat0,10%and20%ishigh.Theconcretestrengthofrecycledaggregateperviousconcreteisthebestwhenthecontentofrecycledfinepowderis0,andthewearresistanceofrecycledaggregateperviousconcretecanbeimprovedwhenthecontentofrecycledfinepowderis10%,andthepermeabilityofrecycledaggregateperviousconcretecanbesignificantlyimprovedwhenthecontentofrecycledfinepowderis20%.
