25 Years Working with Green Steel Slag Concrete Santamaría, Amaia Revilla Cuesta, Víctor Setien, Jesús Vegas, Iñigo González, Javier Jesús Electric Arc Furnace Slag Green concrete Mechanical behavior Concrete durability Reinforced concrete Industrial production of iron and steel within Spain has historically been situated in the north area of Spain. Although a major economic activity for the region, the industry also generates large volumes of waste that have hitherto been dumped in unsightly landfill sites. Over 25 years ago, a group of engineers and researchers from the same area set themselves the challenge of regenerating this waste. In this study, the advances developed in the technology of green slag concrete are reviewed, focusing on the expertise that the research group has accumulated over the past 25 years. Electric arc furnace slag is a stony material that is now often used as aggregate in hydraulic and bituminous mixes. Its use in hydraulic cement-based materials and the important properties of slag aggregates for mix workability are analyzed. Likewise, the mechanical behavior and the durability of slag concrete specimens is presented, paying special attention to expansive compounds and to the performance of electric arc furnace concrete in marine environments. In addition, real scale elements manufactured with slag concrete and their behavior are analyzed, as well as the advantages of applying current standards to their design. Finally, new lines of research are discussed for the use of electric arc furnace slag in cement-based materials. 2025-02-26T11:39:26Z 2025-02-26T11:39:26Z 2025-02-26T11:39:26Z 2023-06 info:eu-repo/semantics/conferenceObject 978-3-031-32518-2 2366-2557 http://hdl.handle.net/10259/10258 10.1007/978-3-031-32519-9 2366-2565 eng Building for the Future: Durable, Sustainable, Resilient (fib Symposium). 2023, V. 349, p. 816-825 https://link.springer.com/chapter/10.1007/978-3-031-32519-9_80 info:eu-repo/semantics/openAccess Springer
