Effect of Recycled Aggregate and Iron Slag in Concrete ...

These Iron slag are materials which does not have a higher scrap value and are considered waste. Concrete wastes from building demolition are dumped and they cannot be recycled. They even pollute the atmosphere and are hard to dispose. In this work, the effect of iron slag and recycled aggregate in the concrete were studied.
