再生骨料混凝土的研究和应用能解决日益发展的建筑业带来的环境问题，通过对乌鲁木齐地区建筑业进行调研，具体分析了乌鲁木齐地区废弃混凝土的现状，将不同来源的废弃混凝土破碎筛分后，分为I、II、III类，对这三类再生细骨料进行性能测试。试验结果表明：I、II、III类再生细骨料所配制的再生砂浆，用水量随着取代率的增大而增大，保水性降低，强度降低；建议I类再生细骨料取代率不宜超过50%，II、III类再生细骨料不宜超过30%。

Research and application of recycled aggregate concrete can solve the environmental problems brought about by the growing construction industry.By the Investigation and research on Urumqi area construction,analysis the situation of waste concrete in Urumqi, After crushing and screening different sources of waste concrete,it divided them into I,II,III categories,test results of the product proper-ties were also given.The results showed that this experiment used recycled fine aggregate of I ,II,IIIcategories to prepare recycled mortar, water consumption was increasing while water-retaining capacity and compressive strength was reducing with the replacement rate in-creasing.So it recommended that the replacement ratio of class I recycled fine aggregate should not exceed 50%and II ,III class recycled fine aggregate should not exceed 30%.
