Slag Cement Concrete Durability

When substituted for portland cement in quantities between 25% and 65%, slag cement plays a vital role in reducing permeability in concrete. SCIC #6, Reducing Permeability, explains how low-permeability concrete has a reduced potential for corrosion of reinforcing steel, and provides a brief discussion of how standard test method ASTM C1202 measures permeability.
