The main components of steel slag (SS) is shown in Table 1. Mason B [47] proposed that the basicity value calculated from the chemical composition of steel slag M = [ω C a O + ω M g O] / [ω S i O 2 + ω P 2 O 5] can be used to evaluate the activity of SS. In this study, the value of M is 2.71, which is high basicity slag.
