Abstract With the rapid development of lithium salt industry, the storage of lithium slag has been increasing year by year. Using the ground lithium slag as a mineral admixture in concrete can effectively solve the stock problem. In this study, fluidity and fluidity loss over time, rheological parameters, Zeta potential were measured to investigate the effect of lithium slag fineness on the rheological properties of cement paste with superplasticizers. The results showed that when the content of lithium slag was constant (i.e., 15%), the initial yield stress and plastic viscosity of the system increased with the increase of specific surface area of lithium slag, and the initial fluidity of the system decreased with the increase of specific surface area of lithium slag. The fluidities of all the systems with and without lithium slag began to decrease after 60 minutes, and the fluidity loss grew with the increase of the specific surface area of lithium slag. Compared to the pure cement system, fluidity losses of three systems with lithium slag were much smaller. The initial Zeta potential of systems with lithium slag decreased obviously, and the decline diminished gradually within 60 minutes and tended to be stable after 60 minutes. The Zeta potential of systems incorporating lithium slags with different finenesses decreased with the increase of specific surface area of lithium slag.

Key words： lithium slag fineness rheological properties Zeta potential fluidity loss
