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

Slag cement strength

Slag cement increases the compressive and flexural strength of conventional concrete (Figures 1 and 2) and is often a vital component in producing high strength concrete. 28-day strengths generally increase as the percentage of slag cement increases, up to about50 percent slag cement as a percent of cementitious material.
