Recycled concrete micropowder-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 recycled concrete micro powder-slag based geopolymer cementing material and a preparation method thereof. The material comprises 50-80 parts of recycled concrete micro powder, 20-50 parts of blast furnace granulated slag, 11-26 parts of an exciting agent, 38-44 parts of a solvent and 12-19 parts of bacillus. The preparation method comprises the following steps: preferentially preparing the exciting agent, then mixing the exciting agent with the recycled concrete micro powder and the blast furnace granulated slag, finally inoculating bacillus, and fully stirring and mixing to form the recycled concrete micro powder-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，具体涉及一种再生混凝土微粉‑矿渣基地聚物胶凝材料及其制备方法。材料包括再生混凝土微粉50～80份、高炉粒化矿渣20～50份、激发剂11～26份、溶剂38～44份、芽孢杆菌12～19份。制备时优先制备激发剂，再与再生混凝土微粉和高炉粒化矿渣混合，最后接种芽孢杆菌，充分搅拌混合形成再生混凝土微粉‑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。
