Time-resolved X-ray Tomography imaging and Raman mapping for in situ tensile tests on polymers loaded with Electric Arc Furnace steelmaking

Steel slag is one of the most common wastes produced by the steelmaking process1. Since the world
steel-request has increased during the last decades, the need to upcycle these slags has become
more demanding and urgent. In this framework, Electric Arc Furnace steelmaking slags (EAF-slags)
represent a real challenge for the upcycling processes, because of their heterogeneous composition
due to the presence of different metal oxides (e.g., FeO, Ca2SiO4, Mg2SiO4, Ca12Al14O33) at different
size ranges. Going through the state-of-the-art, these slags present various revalorization
potentialities, such as filters for P-removal from wastewater2, additives for Portland cement3, and
fillers for polymers4.
