Grouting material for gypsum/mirabilite karst foundation as well as preparation method and application of grouting material
The invention provides a grouting material for a gypsum/mirabilite karst foundation as well as a preparation method and application of the grouting material. The grouting material for the gypsum/mirabilite karst foundation comprises the following components in parts by mass: 70-92 parts of blast furnace slag powder, 8-30 parts of steel slag powder and 250-350 parts of water. The blast furnace slag powder and the steel slag powder of the grouting material provided by the invention are subjected to high-temperature melting and rapid cooling in the forming process, so that the structures of the grouting material are relatively compact and stable, and hydration reaction with water is avoided due to the structural stability; when the grouting material reaches an environment with gypsum/mirabilite, calcium oxide and aluminum oxide in the blast furnace slag powder and the steel slag powder can generate ettringite with sulfate ions in the gypsum/mirabilite, and the ettringite is attached to a gypsum/mirabilite interlayer, so that the effect of blocking corrosion is achieved, and the stability of a gypsum/mirabilite karst foundation is improved.
本发明提供了一种用于石膏/芒硝岩溶地基的注浆料及其制备方法和应用，上述用于石膏/芒硝岩溶地基的注浆料包括以下质量份数的组分：高炉矿渣粉70～92份，钢渣粉8～30份，水250～350份。本发明提供的注浆料的高炉矿渣粉和钢渣粉在形成过程中均经历了高温熔融和快速冷却，使得其结构相对较为致密和稳定，这种结构稳定性避免了与水发生水化反应；当上述注浆料到达具备石膏/芒硝的环境时，高炉矿渣粉和钢渣粉中的氧化钙和氧化铝可以与石膏/芒硝中的硫酸根离子生成钙矾石并附着石膏/芒硝夹层上，从而达到阻断溶蚀的效果，进而提高了石膏/芒硝岩溶地基的稳定性。
