The invention provides a solid waste cementing material for building 3D printing as well as a preparation method and application of the solid waste cementing material. The preparation method comprisesthe following steps: screening cement slag, coal gangue, coal slag and blast furnace slag in solid wastes in building wastes; putting the screened cement slag, coal gangue, coal slag and blast furnace slag into crushing equipment for crushing; and fully mixing cement slurry, coal gangue, coal cinder and blast furnace slag powder, then adding water, adding cement and a concrete surface enhancer after wet grinding, and putting the mixture into a stirrer to be fully mixed. Solid wastes in the building wastes are classified and recycled one by one, the cement slag, the coal gangue, coal slag andthe blast furnace slag in the solid wastes are screened out, crushing and wet grinding are conducted through the crushing equipment, then the cement and the concrete surface enhancer are added, the mixture is put into the stirrer to be fully mixed, and the solid waste cementing material is obtained. Reutilization of building solid wastes is effectively achieved, the 3D printing cost of buildings is reduced, resource reutilization can be improved, and green cyclic development of the building field is promoted.
本发明提供了一种用于建筑3D打印的固废胶凝材料及其制备方法和应用，包括将建筑垃圾中的固体废弃物筛选其中的水泥渣、煤矸石、煤渣和高炉渣；将筛选的水泥渣、煤矸石、煤渣和高炉渣放入到粉碎设备中进行粉碎；将水泥渣、煤矸石、煤渣和高炉渣粉末充分混合后加水，湿磨后加入水泥和混凝土表面增强剂，放入搅拌机中充分混合。本发明通过将建筑垃圾中的固体废弃物进行逐一分类回收，筛选其中的水泥渣、煤矸石、煤渣和高炉渣，采用粉碎设备进行粉碎，湿磨后加入水泥和混凝土表面增强剂，放入搅拌机中充分混合，获得固废胶凝材料。有效实现建筑固废的再利用，降低建筑物3D打印的成本，有利于提高资源再利用，促进建筑领域绿色循环发展。
