In this research, iron ore tailing (IOT) is utilized as the cementitious material to develop an ecofriendly ultrahigh performance concrete (UHPC). The UHPC mix is obtained according to the modified Andreasen and Andersen (MAA) packing model, and the applied dosage of IOT is 10%, 20%, and 30% (by weight), respectively. The calculated packing density of different mixtures is .
