2018.1.1  As a result, there are too many factors affecting reactivity of slag. When cooled slowly in air, the molten slag crystallizes to form inert calcium magnesium silicates, such as melilite, merwinite, and monticellite, smaller amounts of calcium silicates, and pseudowollastonite (Mindess et al., 2008). Thus, in order to obtain a good reactivity ...
