摘　　要：国内对于铁尾矿砂混凝土的研究越来越多,但铁尾矿砂混凝土的力学性能研究处于初始阶段。本试验利用铁尾矿砂完全取代天然砂,利用矿物掺合料等手段对铁矿尾砂混凝土配合比进行优化,研究铁尾矿砂混凝土的轴心抗压强度与立方体抗压强度的关系,结果表明,其二者的比值在0.8～0.9之间。More and more study on ferrous mill tailing concrete.On basis of investigation on properties of ferrous mill tailings,the strength of concretes were studied by substituting ferrous mill tailings for natural sand and crashed stone,and the mix proportion was optimized by means of mineral admixtures.The result of this experimentation shows that the ratio of the prism compressive strength of the ferrous mill tailing concrete and cubic compressive strength is between 0.8 and 0.9.

关 键 词：铁尾矿砂 混凝土 立方体抗压强度 轴心抗压强度
