THE UTILIZATION OF INDUSTRIAL BY-PRODUCTS IN BLENDED CEMENTS

Approximately 85 million tons of portland cement are produced annually in the United States. However, less than one million tons of blended cement containing suitable waste or by-product materials, such as fly ash or blast furnace slag, are produced. In view of the potential for by-product utilization and raw materials and energy conservation, the advantages of increased use of blended cement should be considered. The potential for blended cement production and utilization and the advantages and limitations of utilization are discussed. The limitations imposed on the use of blended cements by standards and other factors are discussed. The technical benefits from the use of blended cements are considered.
