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.

Fly Ash: Roman StructureIn fact, the term “pozzolana” is derived from the name of an Italian city — Pozzuoli — that is regarded as the birthplace of ash concrete technologies.

Famed Roman structures such as the Pantheon and Colosseum, as well as many roads and aqueducts, are still standing over 2,000 years after their construction — in part because of the durability of their ash-based concrete.
