Objective
The ECO-SLAG-CEM project aims to develop high-performance, low-carbon cements using modified Electric Arc Furnace (EAF) slag. The project addresses the significant CO2 emissions from the cement and steel industries, which together account for approximately 14% of global CO2 emissions. The primary objective is to enhance the reactivity of EAF slag through high-temperature treatments and bio-based activation systems, enabling the formulation of high-performance, low-carbon binders to replace the declining availability of granulated blast furnace slag (GBS).To achieve this, the project follows a twofold approach: high-temperature treatments to increase the intrinsic reactivity of EAF slags and the development of tailor-made activation systems, including the use of bio-based chelatants to pre-treat slags and accelerate hydration. A further focus of the project is the presence and mobility of Fe and heavy metals to ensure durability and compliance with environmental standards. The relevance to the work program lies in its alignment with the Horizon Europe Pathfinder Challenge ""Towards cement and concrete as a carbon sink."" The project aims to develop low-carbon binder technologies, optimize clinker reduction, and provide valuable data on the structure and behavior of Fe-bearing slags. By valorizing EAF slag, the project supports the decarbonization of the cement industry and adds value to the steel production process, making it easier to adopt globally and boosting the competitiveness of European steel production. The project involves collaboration between various partners, including universities, research institutes, and industry players, ensuring a comprehensive and interdisciplinary approach. The expected outcomes include the development of treatment strategies for EAF slags, the introduction of bio-based accelerators, and the formulation of high-performance hydraulic binders, contributing to the sustainability and competitiveness of the EU cement & steel industries.""
