Normally, the hydration of BOF slag releases a lower heat compared with the carbonation of BOF slag, suggesting that steel slag has a relatively higher carbonation reactivity. For example, the cumulative heat release of BOF slag hydration is only 30 J/g during a period of 24 h, while that of BOF slag carbonation is 95 J/g within a period of 60 min.
