Geopolymer impermeable material and preparation method thereof
The invention provides a geopolymer anti-seepage material and a preparation method thereof, and belongs to the technical field of engineering material preparation, the geopolymer anti-seepage material takes red mud, C-type fly ash and quicklime powder as basic raw materials, and takes a mixed solution of an alkaline solution and water glass as an alkaline activator. The raw materials adopted by the invention are solid wastes, are low in price, have the characteristics of low permeability, high strength and good durability, and can be directly poured into a water inrush area after the raw materials and the alkaline excitant are prepared when being applied to the water inrush area of the tunnel fault fracture zone; as the raw materials contain the water reducing agent, the preventing agent, the early strength agent and the high CaO, the water consumption for stirring is reduced, the water permeability is reduced, the early strength speed of the geopolymer anti-seepage material is improved, the final setting time is greatly shortened, and the geopolymer anti-seepage material has certain compressive strength. The strength of the geopolymer is further improved along with the gradual increase of the temperature and the humidity.
本发明提供一种地聚物防渗材料及其制备方法，属于工程材料制备技术领域，所述地聚物防渗材料以赤泥、C类粉煤灰和生石灰粉为基本原料，以碱性溶液和水玻璃的混合溶液作为碱性激发剂。本发明采用的原料为固体废弃物，价格低廉，并且具备低渗透、高强度、耐久性良好的特点，在应用于隧道断层破碎带突涌水区域中，在配制好原材料和碱性激发剂后可直接将胶凝结构浇筑于突涌水区域中，因原材料中含有减水剂、防止剂、早强剂和高CaO，减少搅拌用水量、降低透水性和提高地聚物防渗材料前期强度涨速，大大缩短最终凝结时间，并具备一定的抗压强度。随着温度和湿度的逐渐上升，地聚物的强度进一步提高。
