All-solid waste composite powder for cementing material and preparation method of all-solid waste composite powder
The invention provides all-solid waste composite powder for a cementing material and a preparation method of the all-solid waste composite powder, and belongs to the field of building materials. The all-solid waste composite powder comprises molten iron desulfurization slag, electric furnace slag and refining slag. The method comprises the following steps: mixing the molten iron desulfurization slag, the electric furnace slag and the refining slag, feeding the mixture into a superfine tire vertical mill by adopting a conveying belt, and obtaining 700-800-mesh solid waste composite powder through winnowing equipment under the action of mechanical force of a millstone and a grinding roller. The problems that the molten iron desulfurization slag is high in sulfur content and difficult to apply in the building field are solved; in order to solve the technical problems of difficulty in grinding steel slag, poor stability and poor hydration activity in the prior art, the solid waste composite powder of the high-dosage molten iron desulfurization slag for the cementing material is formed by grinding the superfine tire vertical mill, so that the use amount of cement and blast furnace water slag can be reduced, the purpose of reducing carbon in the field of cementing materials is achieved, and the industrial development requirements of energy conservation, environmental protection and circular economy at present are met.
本发明提供了一种胶凝材料用全固废复合粉及其制备方法，属于建筑材料领域。该全固废复合粉包括铁水脱硫渣、电炉渣与精炼渣。本发明将铁水脱硫渣、电炉渣与精炼渣进行混合后，采用输送带将上述混合物送入超细轮胎立磨，在磨盘与磨辊的机械力作用下，通过风选设备，获得700‑800目固废复合粉。本发明解决了铁水脱硫渣受到含硫量高，难以在建筑领域应用的难题；钢渣难磨、安定性差与水化活性差的技术难题，利用超细轮胎立磨粉磨形成胶凝材料用高掺量铁水脱硫渣的固废复合粉，可以减少水泥、高炉水渣的用量，实现胶凝材料领域降碳减碳目的，符合当前节能环保、循环经济的产业发展要求。
