Water-blended quick-hardening metakaolin-based geopolymer material for pouring porous asphalt mixture and preparation method of water-blended quick-hardening metakaolin-based geopolymer material
The invention discloses a water-blended quick-hardening metakaolin-based geopolymer material for pouring a porous asphalt mixture, which is mainly prepared by compounding the following components in percentage by mass: 15-25% of solid sodium silicate, 20-28% of metakaolin, 6-12% of coal ash, 2-4% of sodium hydroxide, 25-35% of water, 5-15% of fine sand, 0.1-5% of expanding agent and 0.1-2% of coupling agent. The metakaolin-based geopolymer grouting material is a metakaolin-based geopolymer powder material with specific strength of 15-25MPa and controllable dry shrinkage rate of-0.1%-0.1% after being directly mixed with water, and effectively solves the problems of tedious steps, time and transportation for preparing alkali activator liquid in advance in the traditional geopolymer grouting material. The geopolymer material mixed with water has good pouring fluidity, can quickly form strength, reduces the early cracking tendency of slurry, and is suitable for popularization and application.
本发明公开了一种多孔沥青混合料灌注用兑水快硬型偏高岭土基地聚物材料，按质量百分数计，其主要由15～25％固体硅酸钠，20～28％偏高岭土，6～12％粉煤灰，2～4％氢氧化钠，25～35％水，5～15％细砂、0.1～5％膨胀剂、0.1～2％偶联剂复配而成，是一种直接兑水后可快速形成15～25MPa特定强度且‑0.1％～0.1％干缩率可控的偏高岭土基地聚物粉体材料，有效解决了传统地聚物灌浆材料需要提前制备碱激发剂液体的繁琐步骤和时间以及运输问题，兑水后的地聚物材料具有良好的灌注流动性、快速形成强度、降低浆体早期开裂倾向，适合推广应用。
