Electric arc furnace slags (EAFS) are by-products of electric steelmaking processes. In 2024, approximately 30% of global steel produced out via the EAF route, generating an estimated 283 Mt of EAFS annually. This volume is expected to rise as major European steel producers continue the electrification of their operations to reduce CO2 emissions.
Despite their significant CaO and SiO2 contents, EAFS currently have no established use as supplementary cementitious materials. Their limited reactivity, coupled with the absence of relevant certifications and standards for construction materials, has been a key barrier to their use. Over the past three years, however, advancements in granulation, chemical modification, and carbonation have demonstrated technically and economically viable pathways for incorporating EAFS as supplementary cementitious materials (SCMs).
This presentation will outline the technical advantages, remaining challenges, and current technological readiness of the principal EAFS-to-SCM beneficiation strategies.
Presenter
Simon Blotevogel studied environmental engineering and geoscience from the Technical University of Braunschweig and the University of Toulouse. He earned his PhD in geochemistry from the University of Toulouse in 2017. Following his doctoral studies, Simon joined the EU-funded Actislag project at LMDC Toulouse, where he investigated the mechanisms controlling the reactivity of ground-granulated blast-furnace slags. His contributions to this field were recognized with the Klaus Dyckerhoff Prize for Young Scientists in 2023. In 2022, Simon became part of Ecocem Materials, where he is leading a research group focused on the utilization of electric arc furnace slags as cementitious materials. Since 2025, he serves as coordinator of the EU-funded Eco-Slag-CEM research project, bringing together eight partners to advance innovative approaches for incorporating electric arc furnace slags in cement.
