摘　　要：在装修垃圾再生骨料的技术性能测试分析的基础上,研究了装修垃圾再生骨料占比对再生混凝土砖力学和变形性能的影响规律。对比研究了装修垃圾再生骨料和工程垃圾再生骨料的基本性能,结果表明:与工程垃圾再生骨料相比,装修垃圾再生骨料含泥量、压碎指标更高,表观密度更小,骨料性能更差。对装修垃圾再生骨料及工程垃圾再生骨料不同占比的再生混凝土砖的力学性能进行试验研究,结果显示:再生混凝土砖的抗压强度随着装修垃圾再生骨料占比的提升而降低,吸水率和干燥收缩率随着装修垃圾再生骨料占比的提升而升高,装修垃圾再生骨料对再生混凝土砖的力学性能具有一定负面影响。Based on the technical performance test analysis of the decoration waste recycled aggregate,it studies the influence of the amount of decoration waste recycled aggregate on the mechanical and deformation properties of recycled concrete brick.The basic performances of the decoration waste recycled aggregate and the engineering waste recycled aggregate were compared.The results show that the recycled waste aggregate has higher mud content,higher crushing index and smaller apparent density than the recycled aggregate of engineering waste.The aggregate performance is even worse.The mechanical properties of recycled concrete bricks with different amounts of decoration waste recycled aggregate and engineering waste recycled aggregate were studied.The results show that the compressive strength of recycled concrete bricks decreases with the increase of the amount of decoration waste recycled aggregate.The water absorption rate and the drying shrinkage rate increase with the increase of the amount of decoration waste recycled aggregates.The decoration waste recycled aggregate has a certain negative impact on the mechanical properties of recycled concrete bricks.
