The overall objective of this research effort was to provide a potentially commercial thermal treatment of fly ash to decrease the interaction between fly ash and the surfactants used to entrain air in concrete when fly ash replaces a portion of the Portland cement in oncrete. The thermal treatment resulting from this research effort, and described in this report, fulfill the above objective. This report describes the thermal treatment developed and applies the treatment to six different fly ashes subsequently used to prepare concrete test cylinders hat show little or no difference in compressibility when compared to concrete test cylinders prepared using untreated fly ash.
