Steel slag-silicon manganese slag synergistic cementing material and preparation method thereof
The invention provides a steel slag-silicon manganese slag synergistic cementing material and a preparation method thereof, and belongs to the field of building materials. The cementing material comprises silicomanganese slag A, silicomanganese slag B and carbon steel slag. The active factor H of the cementing material is more than or equal to 250 and less than or equal to 400. The preparation method comprises the following steps: mixing the silicon-manganese slag A, the silicon-manganese slag B and the carbon steel slag, feeding the mixture into a tire vertical mill by adopting a conveying belt, and obtaining the steel slag-silicon-manganese slag synergistic cementing material through winnowing equipment under the action of mechanical force of a millstone and a grinding roller. The problems that the gelling activity of the steel slag micro-powder is limited, and the stability is poor due to the fact that the steel slag micro-powder contains f-CaO are solved; meanwhile, the steel slag-silicon manganese slag synergistic cementing material is formed by grinding through a tire vertical mill and is used for cement and concrete, so that the use amount of the admixture/admixture can be increased, the use amount of the cement is reduced, the purpose of reducing carbon in the field of cementing materials is achieved, and the current industrial development requirements of energy conservation, environmental protection and circular economy are met.
本发明提供了一种钢渣‑硅锰渣协同胶凝材料及其制备方法，属于建筑材料领域。该胶凝材料包括硅锰渣A、硅锰渣B与碳钢钢渣。所述胶凝材料活性因子满足250≤H≤400。其制备方法是：将硅锰渣A、硅锰渣B与碳钢钢渣进行混合，采用输送带将上述混合物送入轮胎立磨，在磨盘与磨辊的机械力作用下，通过风选设备，获得钢渣‑硅锰渣协同胶凝材料。本发明解决了钢渣微粉的胶凝活性有限，且钢渣微粉含有f‑CaO导致安定性差的问题；同时本发明利用轮胎立磨粉磨形成钢渣‑硅锰渣协同胶凝材料用于水泥与混凝土，可以提高掺合料/混合材的用量替的同时，减少水泥用量，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。
