Abstract：In order to explore a new way of lithium slag resource utilization,this paper based on the analysis of physical and chemical properties of lithium slag,the effects of different amounts of lithium slag on the setting time,mechanical properties and dimensional stability of water-based epoxy mortar were studied.The results show that the heavy metal leaching toxicity and ra-dioactivity of lithium slag meet the requirements of relevant national standards,and mechanical grinding can better stimulate the pozzolanic activity of lithium slag;when the lithium slag content replaces 0～12％of cement mass,with the increase of lithium slag content,the setting time of water-based epoxy mortar is increased,the compressive strength,flexural strength and tensile bond strength show a change trend of first increasing and then decreasing,while the shrinkage rate decreases first and then increases;when the lithium slag content is 6％,the compressive strength,flexural strength,tensile bond strength and shrinkage rate of water-based epoxy mortar respectively are 58.8 MPa,14.3 MPa,1.96 MPa and 0.036％,and its mechanical properties and dimensional sta-bility are the most obvious improvement.
