The invention relates to the technical field of cement-based building materials, in particular to a sulfurized and carbonized steel slag-based perforated brick and a preparation method thereof.The sulfurized and carbonized steel slag micro-powder is prepared by sulfurizing and carbonizing steel slag, the hydration activity of the sulfurized and carbonized steel slag micro-powder is improved, the content of free calcium oxide of the sulfurized and carbonized steel slag micro-powder is reduced, and the problem of poor stability is solved; and finally, the porous brick is prepared from the cement, the vulcanized and carbonized steel slag powder and the artificial aggregate, so that the problems that the existing steel slag solid waste is difficult to treat, is easy to crack after being applied to building materials for a long time and has potential safety hazards are solved, and the recycling efficiency of the industrial solid waste is greatly improved. The industrial solid waste economic value is improved.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种硫化碳化钢渣基多孔砖及其制备方法，本发明利用钢渣进行硫化碳化制备硫化碳化钢渣微粉，提高其水化活性，降低其游离氧化钙含量，解决安定性不良的问题，并利用其与再生骨料和水泥制备人造骨料，最后利用水泥、硫化碳化钢渣粉和人造骨料制备多孔砖，解决了现有钢渣固废处理困难，应用至建筑材料长期使用易开裂，存在安全隐患的问题，大幅提高了工业固废的回收利用效率，提高工业固废经济价值。
