Steel Slag an overview ScienceDirect Topics

For steel slag used as a coarse aggregate in a bound condition, or in a rigid matrix, such as PCC, the resulting integrity and volume stability are basically controlled by the minimum allowable stress of the matrix materials, cement mortar for instance, and the maximum expansion stress, which can be deduced from the expansion force based on
