Abstract

This paper has attempted to show that the cement industry in the United States can accomplish significant reductions in its total energy consumption by intergrinding industrial by-products such as slags, fly ashes, kiln dusts, and possibly other industrial by-products with cement clinker. Further, as seen in many countries this reduction can be accomplished without sacrifice in cement product quality. This study undertook an analysis and evaluation of the utilization of a variety of slags, fly ashes, and kiln dusts in combination with Type I cements from a number of cement plants. Additionally, a significant portion of the project effort was directed on fostering more widespread usage of industrial by-products in blended cement manufacture in the United States and promoting within the industry, ASTM, and other cognizant agencies the adoption of performance specifications applicable to the energy-saving blended cements.

This study was a step in the direction of energy savings that can be attained through blended cement production and use. There are potentially many additional means of further reducing the energy requirements of cement manufacture, as was discussed in the excellent report on the use of energy within the cement industry.
