Fly Ash

We supply Dry and Wet Fly Ash ASTM C 618 class F which is a common request for our
Fly Ash and Raw or Calcined Natural Pozzolan for Use as a Mineral Admixture in Portland
Cement Concrete.
Class F ashes are typically derived from bituminous and anthracite coals and consist primarily of
an alumino-silicate glass, with quartz, mullite, and magnetite also present. Class F, or low
calcium fly ash has less than 12 percent CaO.
