以铁尾矿砂取代天然砂作为细骨料配制自密实混凝土，对其工作性能进行了试验研究，试验结果表明，随着铁尾矿砂掺量的增加，拌合物流变性先增加后降低，当铁尾矿砂掺量超过60％时，自密实混凝土的流动性和填充性明显降低，铁尾矿砂掺量为40％～50％时，拌合物具有良好的工作性。

The paper takes ferrous mill tailings to replace natural sand as fine aggregate to make up self-compaction concrete, and carries out ex- perimental research on the working performance. Research results show that： the rheological behavior of the mixture will firstly increase and sec- ondly reduce with the increasing of ferrous mill railings mixing amount, the fluidity and filling ability of the self-compaction concrete will obviously reduce when the ferrous mill tailings mixing amount exceeds 60% , the mixture will have good working performance when the ferrous mill tailings mixing amount is 40% - 50%.
