绿色混凝土在矿山中的应用

随着矿山开采量的增大,矿山中的采空区充填、井巷支护以及相关配套设施建设中的混凝土用量也越来越大。但是目前这些混凝土的砂石原材料都还是采用传统的开山采矿,挖掘河床获取,既破坏环境也浪费资源。采用尾矿和废石作为混凝土骨料,可减少砂石开采,保护环境,节约成本;利用冶炼厂的粉煤灰和粒化高炉矿渣可以部分替代水泥,并且可以制备性能更优越的混凝土。

Green concert using in mining

With the increasingly excavation amount of the mining, the corresponding amount of concret in shaft and tunnel reinforcement, and filling of the goaf are needed increasingly. But in recently, the traditional mining is still used, and the sandstone material in the concret is obtained from the riverbed method, which will destroy the environment and waste the resource. If the discarded rock and tailings are used for the concret aggregate, there are many advantages like reducing the excavation, protecting the e...
