摘　　要：锂渣粉作为掺合料应用于混凝土中可提高混凝土性能,同时也起到了保护环境的作用。针对乌鲁木齐地区的废弃混凝土,运用正交试验方法将锂渣和再生粗骨料配制C30再生混凝土,通过极差分析法、功效系数法,讨论水灰比、再生骨料取代率及锂渣掺量、对混凝土的工作性能及立方体抗压强度的影响,提出适合乌鲁木齐地区的掺锂渣粉C30再生混凝土配合比。Lithium slag as concrete admixture used in concrete not only can improve performance,but also played a role in protecting the environment. For the waste concrete in Urumqi,we discuss the effect of the water- cement ratio,aggregate rate of substitution and regeneration lithium slag content on the workability and the strength of the recycled coarse aggregate concrete by puting the lithium slag and recycled coarse aggregate into preparation C30 recycled concrete through the orthogonal experiment method,and use the method of poor analysis,efficacy coefficient method. On this basis,we proposed the C30 recycled concrete mixed with lithium slag for Urumqi region.
