Fly ash is a byproduct of burning coal and is often used as a replacement for some of the cement in concrete mixtures. The addition of fly ash improves the workability and strength of the concrete. Gypsum is added to control the setting time of the concrete mixture.

The strength of fly ash mixture often needs to be enhanced for its better utilization in geotechnical and environmental applications. Many fly ashes often improve their strength with lime but may not meet the requirements. Gypsum, which reduces the lime leachability, further improves the strength.
