Method for preparing green concrete by mixing iron tailing superfine sand and natural sand
The invention provides a method for preparing green concrete by mixing iron tailing superfine sand and natural sand. The method comprises the following steps: step 1, preparing iron tailing slag into the iron tailing superfine sand with the particle size of 1-4mm; 2, the sand grains prepared in the step 1 and natural sand are mixed and stirred to prepare mixed sand; and 3, mixing and stirring cement, mixed sand, coarse aggregate, an admixture, a pumping agent and water to prepare the green concrete.
本发明提供了一种铁尾矿特细砂与天然砂混合制备绿色混凝土的方法,包括下述步骤:步骤1:将铁尾矿渣制备成粒径1‑4mm的铁尾矿特细砂;步骤2:将步骤1制得的砂粒与天然砂混合搅拌制得混合砂;步骤3:将水泥、混合砂、粗骨料、掺合料、泵送剂和水混合搅拌制得绿色混凝土。
