Fly ash-based geopolymer material for pouring porous asphalt mixture and preparation method of fly ash-based geopolymer material
The invention relates to the technical field of road building materials, in particular to a fly ash-based geopolymer material for pouring a porous asphalt mixture and a preparation method of the fly ash-based geopolymer material. The fly ash-based geopolymer material for pouring the porous asphalt mixture comprises the following components in percentage by mass: 16-28% of solid sodium silicate, 1-5% of sodium hydroxide, 44-52% of fly ash, 10-22% of standard sand, 0.1-4% of an expanding agent, 0.1-2% of a coupling agent and 0.1-2% of an early strength agent. The method has the advantages that the porous asphalt mixture is poured by utilizing the waste fly ash, so that the method is energy-saving and environment-friendly, carbon emission is reduced, and recycling of solid wastes is realized; after being mixed with water on site, the concrete has good flowability and permeability and can quickly form strength, so that the construction time and the construction cost are reduced; the mixture has the advantages of high temperature performance, high water stability, durability and the like, and is suitable for popularization and application.
本发明涉及道路建筑材料技术领域，特别涉及一种多孔沥青混合料灌注用粉煤灰基地聚物材料及制备方法。本发明的多孔沥青混合料灌注用粉煤灰基地聚物材料按质量百分比计，包括：固体硅酸钠16～28％、氢氧化钠1～5％、粉煤灰44～52％、标准砂10～22％、膨胀剂0.1～4％、偶联剂0.1～2％、早强剂0.1～2％。优点：利用粉煤灰废弃料实现灌注多孔沥青混合料，节能环保，减少碳排放，实现固体废弃物的再循环利用；兑水可直接使用，便于储存和运输，现场兑水后具有良好的流动性和渗透性，可快速形成强度，降低了施工时间和施工成本；混合料能有效兼顾高温性能、水稳定性强，具有耐久性等优点，适合推广应用。
