Slag cement should be substituted for Portland cement on a onetoone basis by mass. Specific gravity of slag cement ranges from 2.85 to2.94, depending upon the slag cement sourceas compared to 3.15for Portland cement. The difference in specific gravity means a greater volume of slag cement will be used to replace the same mass of Portland cement.
