摘　　要：资源化是我国处置建筑固废最重要的思路之一。建筑固废资源化利用对绿色发展具有重要意义。本文利用建筑固废再生骨料制备了一种混凝土透水砖,研究其水灰比、骨灰比和骨料粒径对抗压强度和透水率的影响,最终确定最佳配合比,并分析了不同配合比所制备透水砖的外观尺寸、抗冻性能和耐磨性能。Recycling is one of the most important ideas for the disposal of building solid waste in China.The recycling of building solid waste is great significance to green development.In this paper,a concrete permeable brick was prepared with recycled aggregate from building solid waste,and the effects of water cement ratio,bone cement ratio and aggregate particle size on compressive strength and permeability were studied.Finally,the best mix proportion was determined,and the appearance size,frost resistance and wear resistance of permeable brick prepared with different mix proportion were analyzed.
