The wastes generated from steel industries are known to be as sludge and slag. The problem with some of these by-products is they contain large amount of heavy metals that can be leached out to the environment and cause pollution. Several studies have been conducted on steel slag as a replacement for cement in concrete but it is still not sufficient and well established.
