Benefits of using slag cement - Concrete

Benefits of using slag cement. Q. What are the benefits of using slag cement? A. The hydration products of slag cement are generally found to be more gel-like (less crystalline) than the products of hydration of portland cement; thus, they reduce the permeability of the cement paste (ACI 233R). Slags are used as a replacement of portland cement ...
