Results from the experimentation revealed that, concrete cubes prepared by partially replacing sand with iron ore waste often yield a better compressive strength than a conventional concrete. More so, the densities of concrete cubes were observed to remain consistent but increased slightly, notably at 10% and 20% of waste replacement.
