Gold tailing-based auxiliary cementing material as well as preparation method and application thereof
The invention relates to the technical field of industrial solid waste resource utilization, and particularly discloses a gold tailing-based auxiliary cementing material as well as a preparation method and application thereof. The gold tailing-based auxiliary cementing material comprises the following components in parts by weight: 60-80 parts of gold tailings, 5-20 parts of waste limestone powder, 5-15 parts of gypsum tailings, 5-10 parts of glauberite tailings and 0.5-1 part of a performance regulator, the performance regulator comprises 5%-15% of diethanolisopropanolamine, 10%-20% of sodium oleate and 70%-85% of an alcohol solvent. According to the auxiliary cementing material provided by the invention, various solid hazardous waste synergistic organic performance regulators are added, and a special activation means is matched, so that the reaction activity of the gold tailings is remarkably improved, various mineral micro-powder is excited to react to generate more hydration products, the mechanical property of the material is effectively improved, and the service life of the material is prolonged. The problem of safe treatment of industrial solid wastes is solved, the use amount of cement is effectively reduced, and the concept of green, environment-friendly and sustainable development is met.
本发明涉及工业固废资源化利用技术领域，具体公开一种金尾矿基辅助胶凝材料及其制备方法和应用。所述金尾矿基辅助胶凝材料包括：金尾矿60份～80份，废石灰石粉5份～20份，石膏尾矿5份～15份，钙芒硝尾矿5份～10份和性能调节剂0.5份～1份；性能调节剂包括二乙醇单异丙醇胺5％～15％，油酸钠10％～20％和醇溶剂70％～85％。本发明提供的辅助胶凝材料通过加入多种固体危废协同有机性能调节剂，并配合特殊的活化手段，显著提高了金尾矿的反应活性，并激发各矿物微粉反应生成更多的水化产物，有效提高了材料的力学性能，不仅解决了工业固体废弃物的安全处理问题，还有效减少了水泥的用量，符合绿色环保可持续发展的理念。
