Steel slag-based carbonized material as well as preparation method and application thereof
The invention discloses a steel slag-based carbonized material as well as a preparation method and application thereof. The preparation method of the steel slag-based carbonized material comprises the following steps: adding dry slag, quartz sand tailings, fly ash, stone powder, mineral powder, silica fume and desulfurized gypsum into steel slag, uniformly mixing to obtain a steel slag mixture, adding a reinforcing agent, grinding and uniformly mixing to obtain a mixture; and pressing the mixture into a required green body, performing carbonization treatment, and drying to obtain the steel slag-based carbonized material. The high-performance carbonized product is prepared from compound ingredients such as industrial waste steel slag, furnace slag and fly ash, the problems that the steel slag occupies land and is low in utilization rate are solved, meanwhile, carbon dioxide discharged by industrial waste gas is absorbed and fixed during carbonization, and the method is green and environmentally friendly.
本发明公开了一种钢渣基碳化材料及其制备方法和应用。所述钢渣基碳化材料的制备方法包括如下步骤：在钢渣中加入干炉渣、石英砂尾矿、粉煤灰、石粉、矿粉、硅灰和脱硫石膏，并混合均匀得到钢渣混合物，再加入增强剂并研磨混匀，得到拌合物；将拌合物压制成所需的坯体，然后进行碳化处理后烘干，即制备得到所述钢渣基碳化材料。本发明利用工业废料钢渣、炉渣和粉煤灰等复配料制备得到了高性能碳化制品，解决了钢渣占地、利用率低的问题，同时，碳化时吸收和固定工业废气排放的二氧化碳，绿色环保。
