Preparation method of Bayer process red mud-based geopolymer material system
The invention discloses a preparation method of a Bayer process red mud-based geopolymer material system, and belongs to the technical field of material preparation, and the preparation method comprises the following steps: S1, sorting plastic garbage in household garbage, then crushing and shearing, and carrying out high-temperature refining; s2, after red mud is pretreated, slag powder, cement, water and refined plastic garbage are added and mixed, and a first mixed material is obtained; s3, continuously adding the curing agent, the fine sand and the water glass into the first mixed material, and continuously mixing to obtain a finished product. The Bayer process red mud is used as a geopolymer material, the high-alkali characteristic of the Bayer process red mud is effectively utilized, the cost of an exciting agent is reduced, the purpose of curing alkali metal cations can be achieved, and it is guaranteed that hardened slurry is stable for a long time and environmentally friendly reaches the standard.
本发明公开了一种拜耳法赤泥基地聚物材料体系的制备方法，属于材料制备技术领域，S1、将生活垃圾中的塑料垃圾进行分拣，而后破碎剪切，再进行高温炼化；S2、赤泥预处理后，加入矿渣粉、水泥、水、炼化后的塑料垃圾进行混合，得第一混料；S3、向第一混料中继续加入养护剂、细砂、水玻璃，继续混合，得成品。本发明将拜耳法赤泥用作地聚物材料，不仅有效利用了其高碱特性，降低激发剂的成本，还能达到固化碱金属阳离子的目标，保证硬化浆体的长期稳定与环保达标。
