Many restrictions exist, however, on the utilization of steel slag. When steel slag is used internally, in steel plants, the most obvious problem is that of the enrichment of P and S (Drissen et al., 2009).The Bhilai Steel Plant in India was shut down because of its high S and P content (Das et al., 2007).The amounts of free lime and free MgO are …
