ABSTRACT: Approximately 90% of the coal used in the United States is burned to
produce electricity. As a result, the power plants produce vast quantities of Class F fly
ash. The amount of unburned carbon in these fly ashes has been increasing in the last
decade due to introduction of low nitrogen oxide burners to coal-burning power plants.
Such fly ashes have no value as a concrete additive and require high land-filling costs.
The objective of this study was to investigate potential use of these high carbon
content fly ashes (HCCFA) in sorptive barrier applications. Naphthalene and o-xylene
