The results show that REEs oxide have little effect on the decomposition of carbonate and they improve the sinterability of the raw meal;they also promote the formation of alite and growth of clinker minerals,and have beneficial effect on the uniformity of crystal size and well-distributed minerals. But some REEs result in the corrosion of alite when they are excessive,which may influence the hydration reactivity of alite.When clinker is well sintered, REEs oxide and its tailing improve the strength of cement clinker, and have little effect on setting time of cement.
