Concrete containing copper tailings and preparation method thereof
The invention discloses a preparation method of concrete containing copper tailings. The concrete containing the copper tailings comprises the copper tailings, silica sand, cement, gravel, water, fly ash and an additive. The preparation method comprises the following steps of: weighing the raw materials according to the ratio, sequentially adding the copper tailing sand, the silica sand, the gravel and the cement into a stirrer, stirring and mixing dry powder for 10 seconds, and then sequentially adding the additive and the water to uniformly mix the substances, thereby obtaining the concrete containing the copper tailings. The accumulated waste copper tailings are used as raw materials to replace natural sand to prepare the concrete, so that the problems of environmental pollution and natural sand resource exhaustion caused by accumulation of the copper tailings are solved, and meanwhile, the engineering cost is reduced. All indexes of the prepared concrete meet national standard requirements of concrete.
本发明公开了一种含有铜尾矿的混凝土制备方法，铜尾矿混凝土包括：铜尾矿、硅砂、水泥、碎石、水、粉煤灰和外加剂。步骤为:按照配比称取各原料，依据铜尾矿砂、硅砂、碎石、水泥依次加入到搅拌机内，进行10s干粉搅拌混合，之后依次加入外加剂和水使其混合均匀，制得含有铜尾矿的混凝土。本发明利用堆积废弃的铜尾矿作为原料代替天然砂进行混凝土的制备，有利于解决铜尾矿堆积造成的环境污染和天然砂资源枯竭的问题，同时降低工程成本。本发明制备的混凝土各项指标均符合混凝土的国家标准要求。
