摘　　要：对不同配合比、不同成型工艺的再生混凝土多孔砖进行抗压强度、含水率、吸水率和干燥收缩试验。通过对比分析烧结黏土砖细骨料取代率和成型工艺对建筑废弃物再生多孔砖性能的影响。结果表明：本试验建筑废弃物再生多孔砖不适用于承重墙的砌筑；原料中掺入30％～50％烧结黏土砖细骨料碎片颗粒有利于提高建筑废弃物再生多孔砖的性能；成型工艺中，增加耙动和振动时间对试样的强度没有显著影响，但能减小试样吸水率和干燥收缩率。Waste recycled porous brick with different mixture ratio and production technology are investigated to study compressive strength,moisture content,water absorption and drying shrinkage performance. By contrast, analyzing the different performance of waste recycled porous brick made of different replacement rate of sintered clay brick particles, and considering the influence of the molding process. The results show that, construction waste recycled porous brick is not suitable for load bearing wall. Adding 30%-50% brick particles is good for the performance of construction waste recycled porous brick. Increasing the rake and vibration time has no significant influence on the strength of the sample, but it can reduce the sampte water absorption and drying shrinkageinmolding techniques.
