In order to investigate the effects of different lithium powder content and different roasting temperature on the mechan-ical properties and rheological properties of cement-based materi-als,the mortar with lithium powder content of 5%,15%,25%and 30%was designed in this paper.After roasting at 300℃,500℃and 700℃,lithium slag powder was mixed into mortar to test the rheological properties and mechanical properties of mor-tar.The results show that the compressive pressure of cement-based materials increases first and then decreases with the in-crease of lithium powder content.The flexural strength increases with the increase of lithium powder content.Different roasting temperatures have great influence on the performance of lithium slag powder,and there are different optimal lithium slag content under different roasting temperatures,and the optimal lithium slag content decreases with the increase of roasting temperature.The water consumption of cement standard consistency at differ-ent roasting temperatures is significantly different,showing that the water consumption of cement standard consistency decreases with the increase of roasting temperature.With the increase of lithium powder content,the water consumption of cement stand-ard consistency decreases first and then increases.
