Lithium slag-based geopolymer filling material as well as preparation method and application thereof
The invention discloses a lithium slag based geopolymer filling material and a preparation method and application thereof, the lithium slag based geopolymer filling material comprises the following components in parts by weight: 30-60 parts of lithium slag, 10-20 parts of fly ash, 10-30 parts of slag, 10-25 parts of phosphogypsum, 5-10 parts of zeolite, 5-20 parts of yellow phosphorus slag, 5-10 parts of an exciting agent, 0.25-0.75 part of an additive and 35-50 parts of water, the mass ratio of the ardealite to the yellow phosphorus slag is (0.7-3.7): 1, and the exciting agent is sodium metasilicate and caustic soda. The lithium slag-based geopolymer filling material disclosed by the invention has the advantages of high strength, high sulfuric acid corrosion resistance, low bleeding rate and excellent flowability while meeting the requirements of heavy metal leaching concentration and low radioactivity.
本发明公开了一种锂渣基地聚物填充材料及其制备方法和应用，所述锂渣基地聚物填充材料，以重量份计，包括如下组分：锂渣30‑60份，粉煤灰10‑20份，矿渣10‑30份，磷石膏10‑25份，沸石5‑10份，黄磷渣5‑20份，激发剂5‑10份，外加剂0.25‑0.75份，水35‑50份，其中，所述磷石膏与黄磷渣的质量比为(0.7‑3.7)：1，所述激发剂为偏硅酸钠和苛性钠。本发明的锂渣基地聚物填充材料在满足重金属浸出浓度及放射性低的同时还具有高强度、高抗硫酸侵蚀性、低泌水率以及具有优良流动性。
