Lithium slag is an industrial solid waste generated during the smelting process of metallic lithium，of which comprehensive utilization has received significant practical significance.Based on this，the effect of lithium slag additive on the burnability of raw materials was investigated.XRD and SEM techniques were applied to characterize the phase composition and microstructure of different clinkers.Meanwhile the changes in compressive strength and pore structure characteristics of cement mortar samples were analyzed.Base on the above results，the improving mechanism of the Portland cement clinker quality were revealed.Experiments showed that when the amount of lithium slag added reached 5%，cement clinker exhibited the best hydration performance.After curing for 3，28 d，and 90 d，the compressive strengths of the adhesive sand samples were as high as 38.16 MPa，58.35 MPa，and 75.61 MPa，respectively.The content of oxides including K2O，Na2O，and TiO2 in the raw material was increased in accompany with a reduction in liquid phase viscosity，after adding lithium slag.This result significantly promoted the dissolution of CaO，accelerates the burning of cement clinker，and contributed to C3S and C3A generation.In addition，Al3+ distributed in lithium slag could enhance its hydration activity by replacing Si4+ in C3S and C2S.Therefore，increasing the addition of lithium slag significantly improved the density of mortar products，and resulted to a decrease in the less multi harmful holes and harmful ones，thus endowing the mortar sample with ideal compressive strength.The research provided the theory basis and technology support for the comprehensive utilization of lithium slag
