Fly ash use in concrete up slightly; overall ash recycling

Dec 18, 2020· Fifty-two percent of the coal ash produced during 2019 was recycled, marking the fifth consecutive year that more than half of the power generating station byproduct in the United States was beneficially used rather than disposed. The volume of fly ash used in concrete, 12.6 million tons, marks a 1 percent increase over 2018 consumption.
