Geopolymer cementitious material based on secondary aluminum ash and preparation method of geopolymer cementitious material
The invention discloses a geopolymer cementitious material based on secondary aluminum ash and a preparation method of the geopolymer cementitious material. According to the invention, the geopolymer cementitious material is prepared by taking secondary aluminum ash, building ceramic powder and waste incineration fly powder as main raw materials under the action of an alkali activator. According to the method, a process is simple, few devices are needed, industrial solid waste serves as the raw material, a solidified body of the prepared geopolymer cementitious material has good compressive strength, a heavy metal leaching concentration is far lower than the heavy metal leaching limit value of waste incineration fly powder landfill, and the solidified body of the geopolymer cementing material can be used as a part of specific building materials. As the geopolymer cementing material is prepared and applied, resource utilization of hazardous waste namely secondary aluminum ash and waste incineration flying powder can be realized, cost is low, environmental benefits are obvious, generalizability is high, and good social, environmental and economic benefits are obtained.
本发明公开了一种基于二次铝灰地聚物胶凝材料及其制备方法，该地聚物胶凝材料以二次铝灰、建筑陶瓷粉、垃圾焚烧飞粉为主要原料，在碱激发剂作用下制得。本发明工艺简单，需要设备少，以工业固废为原料，制得的地聚物胶凝材料固化体具有良好的抗压强度和重金属浸出浓度远低于垃圾焚烧飞粉填埋重金属浸出限值，可用作部分特定的建筑材料。该地聚物胶凝材料制备应用可以实现危险废物二次铝灰与垃圾焚烧飞粉的资源化利用，成本低廉，环境效益明显，可推广性强，具有良好的社会环境经济效益。
