Derived from volcanic ash, natural pozzolan was named after the Italian city Pozzouli located just outside Naples, where it was discovered and utilized by ancient Roman architects as a durable building material.

As a result, over half of the coal fired plants have closed in the US reducing the supply of fly ash typically used in concrete and creating a demand for an alternative, natural pozzolan. As the supply of coal ash diminishes, natural pozzolan is becoming the mainstream choice for concrete producers.
