Phase II of DOE-CBRC Project Completed Successfully

A pallett of bricks awaits firing.Illinois State Geological Survey scientist Mei-In (Melissa) Chou has completed the final report of Phase II of a project (2006-2008) sponsored by the U.S. Department of Energy (DOE) through its Cooperative Agreement with the West Virginia University Research Corporation–Combustion By-products Recycling Consortium (CBRC). The 28-page report, titled Manufacturing Building Products with Fly Ash and Advanced Coal Combustion By-products, showed that fired bricks made with various combinations of fly ash, bottom ash, and flue-gas desulfurization solid materials met ASTM specifications. The addition of bottom ash to the mix formulations increased the redness of the brick color and improved the bricks' engineering properties. The study results have led to two meetings with representatives of a utility plant and associated brick plant to plan for commercialization of fired bricks containing fly ash. The commercialization plan includes a scale-up production demonstration of the technology that examines the benefits of blending bottom ash with fly ash in brick formulation.
