Research progress on resource utilization of lithium slag in construction field
Lithium slag is a waste residue generated during the extraction and extraction of lithium ore resources,which contains a large amount of SiO2 and Al2O3.It can be used as a supplementary cementitious material in the construction field,significantly improving the var-ious properties of the material.Introduced the physicochemical properties and activation methods of lithium slag,including the characteris-tics of the original lithium slag and the influence of different activation methods on its activity.Summarized the research progress of lithium slag as a supplementary cementitious material,emphasized its improvement effect on the mechanical properties and durability of ce-ment-based materials,and methods for improving the activity of lithium slag through physical and chemical activation.Explored the poten-tial of synergistic application of lithium slag and multiple solid wastes,and introduced innovative research on the use of lithium slag in the preparation of aggregates.Finally,it is pointed out that further improvement is needed in the activation method of lithium slag,optimization of synergistic application with multiple solid wastes,and environmental evaluation are the focus of future research.
