Multi-solid-waste alkaline activator as well as preparation method and application thereof
The invention discloses a multi-solid-waste alkaline activator as well as a preparation method and application thereof, and belongs to the technical field of solid waste resource utilization. The multi-solid-waste alkaline activator is prepared from the following raw materials in parts by mass: 15 to 35 parts of red mud, 15 to 35 parts of waste glass and 0 to 12 parts of rice hull ash. The method for preparing the geopolymer cementing material by replacing part of sodium silicate with the multi-solid-waste alkaline excitant comprises the following steps: uniformly mixing sodium silicate, sodium hydroxide and water, standing, adding the multi-solid-waste alkaline excitant, and uniformly mixing to obtain a mixed alkaline excitant; the preparation method comprises the following steps: uniformly mixing fly ash and mineral powder, then adding a mixed alkaline activator, uniformly mixing, pouring, and curing to obtain the geopolymer cementing material. The multi-solid-waste alkaline activator provided by the invention can effectively solve the problems of high cost and high carbon emission caused by using sodium hydroxide compounded water glass (sodium silicate) as an alkaline activator.
本发明公开了一种多固废碱性激发剂及其制备方法和应用，属于固废资源化利用技术领域。本发明的多固废碱性激发剂，包括以下质量份数的原料：赤泥15～35份、废玻璃15～35份、稻壳灰0～12份。采用本发明的多固废碱性激发剂替代部分硅酸钠制备地质聚合物胶凝材料的方法，包括以下步骤：将硅酸钠、氢氧化钠和水混合均匀后静置，然后加入多固废碱性激发剂混合均匀，得到混合碱性激发剂；将粉煤灰和矿粉混合均匀，然后加入混合碱性激发剂，混合均匀后浇注、养护，得到地质聚合物胶凝材料。本发明的多固废碱性激发剂，能够有效解决氢氧化钠复配水玻璃(硅酸钠)作为碱性激发剂造成的成本高以及碳排放高的问题。
