Waste incineration bottom ash-based high-strength geopolymer plugging and filling material and preparation method thereof
The invention provides a waste incineration bottom ash-based high-strength geopolymer plugging and filling material and a preparation method thereof, the polymer plugging and filling material is formed by mixing a solid mixture and a liquid alkali activator, and the mass fraction of the liquid alkali activator is 34.05-37.63%; the solid mixture comprises the following components in parts by weight: 40-70 parts of granulated blast furnace slag, 30-60 parts of municipal solid waste incineration bottom ash and 0.16-0.63 part of an organic modifier; the liquid alkali activator is prepared from water, sodium hydroxide and water glass; the liquid alkali activator is prepared from the following components in parts by weight: 40.09 to 53.16 parts of water glass, 1.56 to 2.87 parts of sodium hydroxide and 0.89 to 14.28 parts of water. The prepared polymer plugging and filling material is high in compressive strength, short in setting time, good in compactness and low in cost.
本发明提供了一种垃圾焚烧底灰基高强度地质聚合物封堵充填材料及其制备方法，所述聚合物封堵充填材料由固体混合物和液体碱激发剂混合而成，其中液体碱激发剂质量分数为34.05％‑37.63％；所述固体混合物包括以下重量分数计的组分：粒化高炉矿渣40‑70份、城市生活垃圾焚烧底灰30‑60份、有机改性剂0.16‑0.63份；所述液体碱激发剂由水、氢氧化钠和水玻璃配制而成；所述液体碱激发剂包括以下重量分数计的组分：水玻璃40.09‑53.16份、氢氧化钠1.56‑2.87份和水0.89‑14.28份。本发明制备的聚合物封堵充填材料抗压强度高且凝结时间短的具有良好密实性且成本低廉。
