The invention provides iron tailings recycled concrete and a preparation method thereof. The amount of raw materials contained in each cubic meter of concrete is as follows: 1100 to 1300kg of recycled aggregate, 480 to 720kg of iron tailings powder, 450 to 780kg of cement, 280 to 360kg of water, and 0.15 to 0.20kg of water glass. The iron tailings recycled concrete according to the invention uses the iron tailings powder and the recycled aggregate as main raw materials to reduce the environmental pollution caused by the iron tailings powder and the construction rubbish, reduce the exploitation of natural sandstone, reduce the production cost, and meet the demand on concrete products by nation-building. 本发明提供了种铁尾矿再生混凝土及其制备方法，每立方米混凝土中包含的原料的用量如下：再生骨料：1100-1300kg，铁尾矿粉：480-720kg，水泥：450-780kg，水：280-360kg，水玻璃：0.15-0.20kg。本发明所述的铁尾矿再生混凝土以铁尾矿粉和再生骨料为主要原料，可减少铁尾矿粉和建筑垃圾对环境的污染，降低天然砂石的开采，降低生产成本，满足国家建设对混凝土产品的需求。
