抄録
Due to the large generation of blast furnace (BF) slag, new recycling processes that produce valuable materials are required. The authors have focused on a hydrothermal treatment of BF slag using waste heat exhausted from iron- and steelmaking processes. Although BF slag contains Al_2O_3, which is well known to have a deteriorating effect on hydrothermal reactions, especially CaO–SiO_2 hydration, it can be successfully solidified by hydrothermal treatment above 523 K. We focused on the contribution of MgO in BF slag to the hydrothermal reactivity in the slag system. The hydrothermal solidification of synthesized CaO–SiO_2–Al_2O_3 and CaO–SiO_2–Al_2O_3–MgO slags were investigated in the present work. The hydrothermal solidification behaviors of slags are discussed based on the degree and type of crystal formation during the hydrothermal process.
