Method for preparing composite cementing material from iron tailing powder, superfine slag powder and desulfurized fly ash
The invention relates to a composite cementing material prepared from iron tailing powder, superfine slag powder and desulfurized fly ash, which comprises the following raw materials in parts by weight, 0-42 parts of iron tailing powder, 41-80 parts of superfine slag powder, 9-28 parts of quick lime, 3-13 parts of desulfurized fly ash and 4-17 parts of gypsum. The preparation method comprises thefollowing steps of: adding the raw materials into a container with good leakproofness, shaking and turning over after sealing, standing for 15 minutes, repeating the operation for 3-4 times, and placing the composite cementing material after standing in a dry environment to obtain the composite cementing material prepared from the iron tailing powder, the superfine slag powder and the desulfurizedfly ash. The composite cementing material is prepared from the iron tailing powder, the superfine slag powder and the desulfurized fly ash, so that the problem of insufficient cementing activity of the iron tailing powder is solved, the utilization rate of the iron tailing powder, the superfine slag powder and the desulfurized fly ash is remarkably increased, the environmental burden is reduced,and the composite cementing material has remarkable economic benefits and social benefits.
本发明一种利用铁尾矿粉、矿渣微粉、脱硫灰制备的复合胶凝材料，包括以下重量份原料：铁尾矿粉0‑42份、矿渣微粉41‑80份、生石灰9‑28份、脱硫灰3‑13份、石膏4‑17份，其制备方法包括以下步骤：将各原料加入密闭性良好的容器，封闭好后进行摇晃、翻倒处理，然后静置15分钟，重复操作3‑4次，将静置好的复合胶凝材料置于干燥环境中，获得一种利用铁尾矿粉、矿渣微粉、脱硫灰制备复合胶凝材料。本发明利用铁尾矿粉、矿渣微粉、脱硫灰制备复合胶凝材料，克服了铁尾矿粉本身胶凝活性不足的问题，显著提高了铁尾矿粉、矿渣微粉以及脱硫灰的利用率，减轻了环境负担，具有显著的经济效益和社会效益。
