Phosphogypsum-containing all-solid waste-based geopolymer grouting material and preparation method thereof
The invention relates to a phosphogypsum-containing all-solid waste-based geopolymer grouting material and a preparation method thereof, the polymer grouting material is composed of a solid waste powder raw material component A and a modified composite activator liquid raw material component B, the ratio of the component A to the component B is 1: (0.65-0.7), and the component A is composed of slag, steel slag, fly ash, coal gangue, carbide slag, metakaolin and phosphogypsum in a mass ratio of (35-60): (10-30): (5-15): (4-10): (4-10): (5-10): (12-20); and the component B comprises water, a composite exciting agent, silica fume, a water reducing agent, an early strength agent and a volume stabilizer in a mass ratio of (72-80): (12-15): (7-11): (0.8-1.7): (0.15-0.2): (0.05-0.1). The phosphogypsum-containing all-solid-waste low-carbon environment-friendly grouting material is generated through rapid polymerization reaction of the multi-source solid waste component A and the modified composite exciting agent component B, the requirement for highway roadbed disease grouting treatment can be met, meanwhile, the solid waste such as the steel slag and the phosphogypsum with the low comprehensive utilization rate is digested, and the utilization rate of the phosphogypsum is improved. The method has the advantages of good social benefit, wide application prospect and the like.
本发明涉及一种含磷石膏全固废基地质聚合物注浆材料及其制备方法，聚合物注浆材料由固废粉体原材料A组分和改性复合激发剂液体原材料B组分组成，A、B组分比例为1:0.65～0.7，A组分组成及质量比为矿渣：钢渣：粉煤灰：煤矸石：电石渣：偏高岭土：磷石膏＝35～60：10～30：5～15：4～10：4～10：5～10：12～20；B组分组成及质量比为水：复合激发剂：硅灰：减水剂：早强剂：体积稳定剂＝72～80：12～15：7～11：0.8～1.7：0.15～0.2：0.05～0.1。本发明利用多源固废A组分和改性复合激发剂B组分快速聚合反应生成一种含磷石膏全固废低碳环保型注浆材料，可满足高速公路路基病害注浆治理的需求，同时消纳钢渣、磷石膏等综合利用率低的固废物，具有社会效益好、应用前景广阔等优势。
