研究了邯郸地区用砖混结构建筑垃圾生成的建筑垃圾人工砂的粒径、堆积密度、吸水率、压碎值指标等基本物理性能，分别以0、50%、100%的建筑垃圾人工砂等量取代天然细骨料配制不同强度等级混凝土，检验混凝土拌合物的性能、力学性能及耐久性能，探讨了建筑垃圾人工砂不同取代率对混凝土性能的影响。试验结果表明，建筑垃圾人工砂完全代替天然砂用于C60及以下强度等级的混凝土中是可行的，随着取代率的提高，混凝土强度有所降低；混凝土强度越高，降低幅度越大。

The basic physical properties of construction waste artificial sand such as particle size, bulk density, water absorption, crushing value index were studied systematically and the construction waste artificial sand was made from con-struction waste of brick structure in Handan region. Different strength grade concrete was prepared by using 0, 50% and 100% of the construction waste artificial sand equivalent to replace mineral fine aggregate. The performance, mechanical properties and durability of the concrete mixture are tested, and the effect of different replace ratio of construction waste artificial sand on the performance of concrete is discussed. The experimental results show that it is feasible that construc-tion waste artificial sand completely replaces natural sand of fine aggregate to prepare less than or equal to C60 strength grade concrete; with the improvement of replacement ratio, concrete strength reduce; the higher the concrete strength is, the bigger the strength reduction is.
