There are three methods to improve the cementitious activity of steel slag, including physical, chemical, and thermal excitation. Physical excitation is the method used to reduce the steel slag's particle size by crushing, grinding, and so on, which can increase steel slag's specific surface area and cementitious activity [ 16, 17, 18, 19 ].
