The invention discloses a lithium slag-based geopolymer cementing material which comprises 30-70 parts of activated lithium slag, 10-50 parts of mineral powder, 5-20 parts of fly ash, 5-15 parts of semi-hydrated gypsum and 0.5-2 parts of a compound additive. The method comprises the following steps: firstly, adding triisopropanolamine and limestone into the lithium slag for grinding and activating, so that the specific surface area of the lithium slag is increased from 150-200m < 2 >/kg to 500-700m < 2 >/kg, and activated lithium slag is obtained for later use; and adding mineral powder, fly ash and semi-hydrated gypsum into the activated lithium slag, uniformly mixing, and adding a compound additive to prepare the hydraulic cementing material-lithium slag-based geopolymer cementing material. According to the lithium slag-based geopolymer cementing material prepared by the method, the solid waste resource lithium slag can be effectively utilized, meanwhile, the risk of solid waste stockpiling and discharging is reduced, and the prepared lithium slag-based geopolymer cementing material is a low-carbon material and can be used for manufacturing various green building material products.
本发明公开了一种锂渣基地聚物胶凝材料，包括活化锂渣30‑70份，矿粉10‑50份，粉煤灰5‑20份，半水石膏5‑15份，复配外加剂0.5‑2份。首先向锂渣中加入三异丙醇胺、石灰石进行粉磨活化，以此将锂渣的比表面积从150‑200m2/kg提高至500‑700m2/kg，得活化锂渣备用；向活化锂渣中加入矿粉、粉煤灰和半水石膏，混合均匀后再加入复配外加剂，可制备出一种水硬性胶凝材料‑锂渣基地聚物胶凝材料。采用本发明制得的锂渣基地聚物胶凝材料能有效率利用固废资源锂渣，同时降低了固废堆存和排放的风险，制得的锂渣基地聚物胶凝材料是一种低碳材料，可用于制造多种绿色建材制品。
