Benefits of using slag cement American Concrete Institute

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).
