摘要:
以铁尾矿砂代替天然河砂拌制混凝土，通过拔出试验研究变形钢筋与铁尾矿砂混凝土之间的粘结性能．制作12组铁尾矿砂混凝土拔出试件，分析其在不同混凝土强度等级(C20、C30、C40)和不同钢筋直径(12 mm、16 mm、20 mm、25 mm)下的平均粘结应力(τ)-滑移(s)曲线，在此基础上研究变形钢筋与铁尾矿砂混凝土的粘结性能，并与普通混凝土相对应的性能进行比较．试验结果表明，钢筋与铁尾矿砂混凝土的粘结性能略优于普通混凝土，铁尾矿砂可以替代普通河砂制作混凝土，所得结论为铁尾矿砂的工程应用提供理论参考．
Abstract:
The ferrous mill tailing has been used to replace river sand to mix concrete, and the bond behavior between deformed bars and ferrous mill tailing concrete was studied by a series of pulling-out test in the paper. Twelve groups of the ferrous mill tailing concrete specimens with different strength grades (C20, C30 and C40) and diameters (12 mm, 16 mm, 20 mm and 25 mm) were made, and the average bond stress (τ) - slip (s) curves were obtained according to data collected in the experiment. Based on this, the bond behavior of deformed bars and ferrous mill tailing concrete are analyzed, which has also been compared with the corresponding behavior of ordinary concrete. The experimental research indicates that the bond capability of deformed bars and ferrous mill tailing concrete is slightly better than that of the ordinary concrete. Therefore, ferrous mill tailing could fully replace river sand to make concrete, which can provide a theoretical reference for engineering applications
