In Korea, the amount of silico-manganese slag discharged was ~0.35 million tons in 2013, and was assumed to be several million tons worldwide. The main chemical components of silico-manganese slag are SiO 2, CaO, MnO, Al 2 O 3, and MgO, as shown in Table 1. Most of them (except for MnO) are oxides that could be expected a pozzolanic reaction.
