Utilization of steel slag as a supplementary cementitious material is limited due to its poor volume stability and weak hydration activity. Moreover, the alkaline minerals of steel slag make it highly susceptible toward carbonation. Thus, this study aims to analyze the impact of accelerated precarbo...
