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. Th

In November 2025, NEU released a new publication, The Low-Carbon Concrete Guide: Materials. The guide examines concrete’s role in global carbon emissions, life-cycle thinking and carbon quantification tools, as well as a full spectrum of binder-level strategies, including SCMs, mineral fillers, blended cements, low-carbon portland cements, and alternative cements. It also introduces aggregate, reinforcement, and water-level pathways, along with supporting concepts such as mix
