Characterization and Reuse of Slag

Dear Colleagues,

Slag is a byproduct generated in metallurgical processes, predominantly composed of oxides. Traditionally considered as a waste, slag is now valued as a resource due to technological advancements and environmental concerns. Its primary application is in civil construction, where it can be used as a base material for paving, in cement production, and as aggregate in concrete and mortar. Additionally, slag has applications in agriculture as a soil conditioner, in the abrasive industry for blasting materials, and in the production of thermal and acoustic insulation. Besides being used as a raw material in various applications, slags can also be rich in strategic metals.

The reuse of slag contributes to the circular economy, reducing the need for new resource extraction and minimizing the environmental impact of metallurgical processes. Thus, slag, once seen as waste, is now a byproduct with multiple applications, exemplifying how innovation and environmental responsibility can turn challenges into opportunities.

This Special Issue invites researchers to submit papers that include original scientific research related to the characterization and reuse routes of slags. The Special Issue focuses on the following topics: (1) Chemical, physical, mineralogical, and environmental characterizations of slags; (2) Processing routes; and (3) The valorization of slags. Other applications of slags are also encouraged for publication in this Special Issue.
