| 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: | An optimal model was established for evaluating the compressive strength,splitting tensile strength,porosity,permeability coefficient and mass loss rate of recycled aggregate pervious concrete based on the grey relational analysis method,and the correlation degree between different content of recycled fine powder and the optimal index set was calculated.The results show that the gray correlation degree of the content of recycled fine powder at 0,10%and 20%is high.The concrete strength of recycled aggregate pervious concrete is the best when the content of recycled fine powder is 0,and the wear resistance of recycled aggregate pervious concrete can be improved when the content of recycled fine powder is 10%,and the permeability of recycled aggregate pervious concrete can be significantly improved when the content of recycled fine powder is 20%. |
