Fly ash reduces costs and provides benefits by decreasing the need for cement production, increasing concrete durability and providing a sustainable method of utilizing coal fired power plants by-products. This research will provide State agencies and industry guidance on how to adjust to the changes in fly ash supply, blending, and quality that are a result of diminished production/availability of fly ash.
