Scheduled International Concrete Sustainability Conference speakers include Hank Keiper of the SEFA Group, who will present “The Future of Fly Ash is Under Our Feet,” during the May 12-14 event in Boston. He will discuss the dwindling availability of coal fly ash suitable for use as supplementary cementitious material in the U.S. due to environmental regulations and market factors. To ensure a future supply of high-quality, Class F fly ash, SEFA Group has modified its proprietary thermal beneficiation process to accept fly ash reclaimed from disposal sites, including both landfills and settling ponds. The adaptation of a proven technology will create a consistent supply of premium fly ash, prevent future disposal of material initially below ASTM C618 grade, and offer existing site
remediation solutions.
