The Future of Fly Ash in Concrete - CarbonCure

2020-12-1  Fly ash, sometimes called flue ash, has been a popular supplementary cementitious material (SCM) since the mid-1900s. Years of research show that fly ash can decrease concrete’s carbon footprint—and its cost—while increasing its strength and workability. For most concrete producers, fly ash is an important ingredient in concrete mix designs.
