Class C & Class F Fly Ash

Charah Solutions supplies both Class C and Class F fly ash from locations around the country. The use of fly ash in concrete products offers benefits in both the hardened and plastic state of concrete.

Fly ash improves hardened concrete with:

Higher Strength

Decreased Permeability

Increased Durability

Reduced ASR (Alkali-Silica Reactivity)

Lower Heat of Hydration

Increased Sulfate Resistance

Concrete product manufacturer and finishers see the following benefits of concrete in its plastic state:

Increased Workability

Lower Water/Cement Ratio

Improved Finishing

Improved Pumpability

Less Material Segregation

In addition to improving the finish product quality, using fly ash in concrete products and other applications not only eliminates the need to dispose of fly ash in landfills, it also significantly reduces the overall carbon footprint and conserves our natural resources by replacing materials that would otherwise have to be mined and processed for these products.
