Fly Ash Concrete
Historical Background of Fly Ash
Long before modern power plants began producing coal fly ash, Roman builders turned to volcanic ash to harness the power of pozzolans.
In fact, the term “pozzolana” is derived from the name of an Italian city — Pozzuoli — that is regarded as the birthplace of ash concrete technologies.
