Acid-excited lithium slag-based geopolymer as well as preparation method and application thereof
The invention discloses an acid-excited lithium slag-based geopolymer as well as a preparation method and application thereof. The acid-excited lithium slag-based geopolymer comprises the following components in parts by weight: 30-60 parts of lithium slag; 25-35 parts of electrolytic manganese residues; 10 to 25 parts of metakaolin; 3-6 parts of magnesium oxide; 1-2 parts of a water reducing agent; 1-2 parts of borax; 100 to 110 parts of a phosphoric acid solution; in the phosphoric acid solution, the mass fraction of phosphoric acid is 40-60%; the particle size of the lithium slag and the electrolytic manganese slag is 200-400 meshes; the particle size of the metakaolin is less than or equal to 200 meshes. The compressive strength and breaking strength of the geopolymer are improved, meanwhile, the metal dissolution amount is low, and the environmental safety is high; the porosity is low, and the sulfate corrosion resistance is high; the two solid waste raw materials of the lithium slag and the electrolytic manganese slag can be utilized at the same time, and the problem that the lithium slag and the electrolytic manganese slag are difficult to treat is solved.
本发明公开了一种酸激发锂渣基地质聚合物及其制备方法和应用。所述酸激发锂渣基地质聚合物，以重量份计，包括如下组分：锂渣30～60份；电解锰渣25～35份；偏高岭土10～25份；氧化镁3～6份；减水剂1～2份；硼砂1～2份；磷酸溶液100～110份；所述磷酸溶液中，磷酸的质量分数为40～60％；所述锂渣、电解锰渣的粒径为200～400目；所述偏高岭土的粒径≤200目。本发明提高了地质聚合物的抗压强度及抗折强度，同时金属溶出量低，环境安全性高；孔隙率低，对抗硫酸盐侵蚀性的能力强；能够同时利用锂渣和电解锰渣这两种固废原料，解决了锂渣和电解锰渣难处理的问题。
