Iron ore tailings were also used in other concrete applications. For example, Das et al. [13] studied the use of IOT to develop ceramic tiles and their study showed, that tiles produced at a maximum of 40% of IOT were superior in terms of scratch hardness and strength, compared to European standard specifications. In a related research, Yao et al. [14] produced …
