Blended Cement - Lehigh Hanson, Inc.
Slag cement is the byproduct of steel production. It is formed by the molten slag in blast furnaces used to process iron ore to make steel. Finely ground limestone can replace 5% to 15% of portland cement. Portland-limestone cements require less energy to produce because the limestone is not pyroprocessed like the portland cement it replaces.
