1. Coal is needed as a reducing agent. “Reduction” is a chemical reaction that turns iron ore (Fe2O3) into pig iron (2Fe). Carbon monoxide (CO) is the crucial ingredient (Fe2O3 + 3CO → 2Fe + 3CO2) and is produced in blast furnaces by burning coal. This also produces carbon dioxide as a waste product

Results show that 35% replacement of natural aggregate by iron ore tailings is optimal. Finally, tests of impermeability, frost resistance, and carbonation resistance were further performed for the concrete specimens with optimal amount of iron ore tailings. The compression performance of the specimens after a durability test was determined
