Fly Ash Sales
Technical Service and Solutions For the Construction Industry
STAR Ash
STAR Fly Ash is a high-quality, specification-grade fly ash for use as a supplementary cementitious material in concrete and concrete products. Coal ash from ponds or landfills is transformed into a consistent, low LOI, Class F fly ash for encapsulated beneficial use. Reclaiming coal ash from ponds provides year-round availability of this post-industrial, recycled material for the construction industry.

What Is Fly Ash?
Fly ash is classified as a Pozzolan: a mineral admixture and a supplementary cementitious material that provides concrete with performance benefits such as water tightness and long-term durability.
Volcanic ash, similar to today’s fly ash in its chemistry, was used as a supplementary cementitious material in concrete dating back to the Roman Empire. This natural Pozzolan was used in structures that have lasted for thousands of years.
Fly ash is used in:
- Ready Mixed Concrete
- Concrete Paving
- Asphalt Paving
- CLSM / Flowable Fill
- Cellular Concrete
- Precast Concrete
- Prestressed Concrete
- Block, Pipe, Vaults, etc.
The use of fly ash in concrete can contribute significant environmental, structural, and economic benefits. The EPA supports the beneficial use of fly ash in concrete, which improves the durability of concrete and prolongs the lifecycle of our roads, buildings, bridges, dams, and other important structures.
