Fly ash-slag based geopolymer cementing material and preparation method thereof
The invention relates to the technical field of solid waste resource recycling and green low-carbon cementing materials, in particular to a fly ash-slag based geopolymer cementing material and a preparation method thereof. The material comprises 66-74 parts of fly ash, 28-32 parts of blast furnace granulated slag, 6-7 parts of an exciting agent, 47-52 parts of a solvent and 3-7 parts of bacillus. The preparation method comprises the following steps: preferentially preparing the exciting agent, then mixing the exciting agent with the fly ash and the blast furnace granulated slag, finally inoculating the bacillus, and fully stirring and mixing to form the fly ash-slag based geopolymer cementing material. The method has the advantages that cement is partially replaced; the economical problems of solid waste resource storage and resource application can be effectively solved; a high-performance material with condensation flow characteristics and mechanical strength characteristics is simple and economical in material taking, rapid and convenient to construct and reliable and stable in curing effect; microorganisms are introduced, so that the impermeability is better improved; the curing effect is good.
本发明涉及固废资源再利用和绿色低碳胶凝材料技术领域，具体涉及一种粉煤灰‑矿渣基地聚物胶凝材料及其制备方法。材料包括粉煤灰66～74份、高炉粒化矿渣28～32份、激发剂6～7份、溶剂47～52份、芽孢杆菌3～7份。制备时优先制备激发剂，再与粉煤灰和高炉粒化矿渣混合，最后接种芽孢杆菌，充分搅拌混合形成粉煤灰‑矿渣基地聚物胶凝材料。优点在于：部分替代水泥；可有效解决固废资源存放和资源化应用经济性问题；兼具凝结流动特性和力学强度特性的高性能材料，取材简易经济，施工快捷方便，固化效果可靠稳定；引入微生物，更好的提升其抗渗性；固化效果好。
