Iron-rich sludge/slag composite geopolymer and preparation method thereof
The invention belongs to the technical field of solid waste comprehensive utilization and building material preparation. The invention particularly relates to a composite geopolymer material prepared by taking industrial solid waste iron-rich sludge and slag as raw materials, and further discloses a preparation method of the composite geopolymer material. Geopolymer materials with different strengths are obtained by utilizing solid waste materials and changing preparation conditions, and the highest strength can reach 31.20 MPa in 28d. According to the solid waste-based geopolymer provided by the invention, the iron-rich sludge and the slag are effectively consumed, the strength of the geopolymer is obviously improved, resources and energy are saved, the problems of pollution and reutilization of the iron-rich sludge and the slag are solved, and the comprehensive utilization of the iron-rich sludge and the slag material is promoted.
本发明属于固体废弃物综合利用和建筑材料制备技术领域。具体涉及一种以工业固体废弃物富铁污泥与矿渣为原料制备的复合地质聚合物材料，并进一步公开其制备方法。利用固体废弃物材料，通过改变制备条件，获得具有不同强度的地质聚合物材料，28d最高强度可达31.20MPa。本发明提出固体废弃物基地质聚合物有效消纳了富铁污泥与矿渣，明显提升地质聚合物强度同时，节约了资源与能源，解决了富铁污泥与矿渣的污染与再利用问题，推动了富铁污泥与矿渣材料的综合利用。
