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.
