Domestic waste incineration fly ash-based geopolymer composite unfired granular material and preparation method thereof
The invention provides a household garbage incineration fly ash-based geopolymer composite unfired granular material and a preparation method thereof, and relates to the technical field of dangerous solid waste recycling. Fly ash subjected to cracking treatment is mixed with mineral powder, fly ash and metakaolin for alkali excitation, a geopolymer material is obtained, then the geopolymer material is washed with water and then cured, and the fly ash-based geopolymer composite material is obtained. The process mode of low-temperature cracking, geopolymer curing and washing dechlorination maintenance is adopted, harmless treatment and resource utilization of the household garbage incineration fly ash are achieved, and the prepared fly ash-based geopolymer composite material is good in performance and can meet the use performance requirements of building materials.
本发明提供一种生活垃圾焚烧飞灰基地聚物复合免烧颗粒材料及其制备方法，涉及危险固体废弃物资源化技术领域。本发明将经裂解处理的飞灰与矿粉、粉煤灰及偏高岭土混合进行碱激发，得到地聚物材料，之后将地聚物材料经水洗后养护，得到一种飞灰基地聚物复合材料。本发明采用“低温裂解+地聚物固化+水洗脱氯养护”工艺模式，实现生活垃圾焚烧飞灰无害化处置及资源化利用，制备得到的飞灰基地聚物复合材料性能佳，可满足建筑材料的使用性能要求。
