As environmental concerns become a critical issue in the sustainability of the steel industry, manufacturing of various kinds of glass-ceramics and related functional materials recycled from post-mortem slags has become an important topic of research.
The slag composition, which was reduced and cooled using this secondary treatment is affected by the operating parameters and thermo-physical properties of the slag, and thus can provide the potential for utilization in highly value-added products such as Portland cement and high-alumina cement. To increase the applications of the reduced slag product, a new cement material as well as slag aggregates from the EAF slags were developed by controlling the composition and morphology through novel methods.
