摘　　要：采集棚户区建筑垃圾,经过破碎和筛分处理,得到再生粗骨料和细骨料,分析细骨料的级配、细度模数;分析粗骨料的粒径、级配。研究结果:再生细骨料为粗砂,级配不合格,不能直接用于混凝土作为细骨料;再生粗骨料符合连续级配要求,可以用于混凝土的拌合。This paper collects construction waste in shantytowns,crushes and sieves to obtain recycled coarse and fine aggregates,analyzes the gradation and fineness modulus of fine aggregates,and analyzes the size and gradation of coarse aggregates.Research results:The recycled fine aggregate is coarse sand,and the grading is unqualified.It cannot be directly used for concrete as fine aggregate.The recycled coarse aggregate meets the requirements of continuous grading,and can be used for concrete mixing.

关 键 词：再生细骨料 再生粗骨料 骨料级配
