This work assessed three types of cement available commercially in terms of strength, porosity, setting and so on to prevent dangers waste of resources and to minimize cost of construction and if such similar commercial cements are mixed with iron-ore tailings. Burham, Dangote and Elephant cement were investigated to ascertain their setting times (both final and initial) using the Vicat apparatus. Iron-ores tailings which is amounting to several tonnes in piles which can in the future, lead to disposal problems was used as additives on these cements. The result shows that the tailings have positive effect on the setting times of the tested cements. Future work will address the contents of tailings which when added would provide the maximum benefit and also the effect on the compressive strength.
