Lithium slag-based early-strength and high-strength cementing material and preparation method thereof
The invention provides a lithium slag-based early-strength high-strength cementing material and a preparation method thereof, and belongs to the technical field of building materials. The cementing material comprises the following components in parts by weight: 10-40 parts of lithium slag, 5-30 parts of red mud and 5-15 parts of an exciting agent, and the exciting agent is at least one of an alkali exciting agent, a salt exciting agent or an organic metal compound exciting agent. During preparation, the lithium slag and the red mud are ground until the specific surface area is greater than 300m < 2 >/kg and are uniformly mixed, and then the mixture is mixed with the exciting agent and the water. The cementitious material disclosed by the invention has certain micro-expansion performance, can compensate volume shrinkage of a conventional cementitious material in a hardening process, and reduces cracks caused by volume shrinkage; meanwhile, according to the cementing material disclosed by the invention, the lithium slag and the red mud are subjected to resource utilization, so that not only is the production cost reduced, but also waste resources are recycled, and the environmental protection pressure is reduced; meanwhile, the cementing material disclosed by the invention is relatively high in final strength, and the application scene and the production benefit of the cementing material are increased.
本发明提供了一种锂渣基早强高强胶凝材料及其制备方法，属于建筑材料技术领域。以重量份计，该胶凝材料包括10～40份锂渣，5～30份赤泥，5～15份激发剂，所述激发剂为碱激发剂、盐类激发剂或有机金属化合物激发剂中的至少一种。在制备时，将锂渣和赤泥研磨至比表面积大于300m2/kg并混合均匀，随后将其与激发剂和水进行混合即可。本发明的胶凝材料，其具有一定的微膨性能，能够对常规胶凝材料在硬化过程中的体积收缩进行补偿，降低因体积收缩而产生的裂缝；同时，本发明的胶凝材料，其将锂渣和赤泥进行资源化利用，不仅降低了生产成本，同时还将废弃资源再利用，降低了环保压力；同时，本发明的胶凝材料，其最终强度较高，增大了其应用场景和生产效益。
