AOD slag has shown promising potential for usage as a carbon-capture construction material due to its high capacity for CO2CO<sub>2</sub> and its low cost. Carbonation curing, a process utilizing CO2CO<sub>2</sub> as a curing agent in concrete manufacturing, enhances the chemical properties of stainless steel slag by stabilizing it. During carbonation, g-C2SC<sub>2</sub>S (di-calcium silicate) in the slag reacts with CO2CO<sub>2</sub> to produce compounds like calcite and silica gel, resulting in increased compressive strength and improved durability of cementitious materials. The incorporation of AOD slag as a replacement material in ordinary Portland cement (OPC) during carbonation curing has been studied, demonstrating positive effects on strength and reduced porosity.<ref>{{cite journal |last1=Moon|first1= Choi |first2=E.J.|last2= Y.C |title=Development of carbon-capture binder using stainless steel argon oxygen decarburization slag activated by carbonation |journal=Journal of Cleaner Production |date=2018 |volume=180 |pages=642–654|doi=10.1016/j.jclepro.2018.01.189 }}</ref>
