Composite cement-based cementing material and preparation method thereof
The invention provides a composite cement-based cementing material and a preparation method thereof, and relates to the technical field of grouting reinforcement. The composite cement-based cementing material comprises a component A, a component B and water, the component A comprises cement and activated lithium slag, and the component B comprises a water reducing agent, water glass and isomeric alcohol polyoxyethylene ether. According to the invention, the activation temperature and the activation time of the lithium slag are obviously reduced by adding the activation aid, the preparation cost of the product is reduced, and the stability and the processability of the cementing material are improved by using the activated lithium slag and the isomeric alcohol polyoxyethylene ether. The composite cement-based cementitious material provided by the invention can realize a relatively high cement replacement amount, not only reduces the emission of industrial wastes, but also reduces the influence on the environment. Meanwhile, no complex equipment or technology is needed in the product preparation process, field operation is easy, the working performance and mechanical performance of the cementing material are improved, meanwhile, the production cost is reduced, and the method is suitable for large-scale application.
本发明提供了一种复合水泥基胶凝材料及其制备方法，涉及注浆加固技术领域。本发明的复合水泥基胶凝材料包括A组分、B组分和水，其中A组分包括水泥、活化锂渣，B组分包括减水剂、水玻璃、异构醇聚氧乙烯醚。本发明通过活化助剂的添加，显著降低了锂渣的活化温度和活化时间，降低了产品的制备成本，通过活化锂渣和异构醇聚氧乙烯醚的使用，改善了胶凝材料的稳定性和加工性能。本发明的复合水泥基胶凝材料能够实现较高的水泥取代量，不仅减少了工业废弃物的排放，也降低了对环境的影响。同时，产品制备过程中无需复杂的设备或技术，易于现场操作，在提高胶凝材料工作性能与力学性能的同时，降低生产成本，适合大规模应用。
