Highlights The IOT were characterized by techniques like XRD and XRF. The raw materials with different IOT addition were synthesized cement clinkers. The addition of IOT did not qualitatively affect the mineralogical phases. The optimum IOT addition for producing good clinker were investigated.
Abstract We report a type of high-magnesium and low-silicon iron ore tailings (IOT) utilized as a raw material replacing clay to produce cement clinkers by conventional sintering process. Properties of the cement clinkers sintered at 1420 °C with different IOT addition, from 0 to 20 wt%, were investigated. The chemical and mineralogical analysis, and microscopic examination showed that IOT addition, up to 10 wt%, has little effect on formation of mineralogical phases. Furthermore, physico-mechanical tests showed the IOT addition within 10 wt% did not negatively affect the quality of the produced cement clinkers, on the contrary, could produce better quality clinkers than without IOT. These findings suggest that the high-magnesium and low-silicon IOT has a huge potential as cement raw materials instead of partial natural resources.
