More on Fly Ash

Fly ash is the fine ash resulting from burning coal in electric utility plants. It is used as a mineral admixture for many high performance concretes. The many performance enhancing properties and the typically lower cost have made fly ash one of the key ingredients in modern concrete production.
 
Fly ash can also be used in geotechnical applications for soil stabilization, as a drying agent, for stabilizing aggregate bases, as a structural fill, for bituminous pavement recycling, and for reducing shrink/swell in expansive clay soils.
