Abstract Effect of cement properties which using a bauxite tailings as admixture was studied. The mineral composition and the particle size distribution of the bauxite tailings were analyzed. The water demand at standard consistency, setting time and compressive strength of the bauxite tailings cement were tested. The results showed that: the original bauxite tailings contain the minerals of a class of kaolinite (halloysite, nacrite, dickite), diaspore and a class of mica (muscovite, potassium mica, polylithionite). Taking the burned bauxite tailings as admixture, the cement standard consistency was higher, the setting time was shortened obviously and the compressive strengths were a little lower than which with the fine blast furnace slag but higher than the fly ash. The burned bauxite tailings and fine blastfurnace slag and fly ash compositing together as admixture, the standard consistency was apt to decrease and the compressive strength increased.
