• Abstract:
  Previous Iowa DOT sponsored research has shown that some Class ; C fly ashes are cementitious (because calcium is combined as calcium ; aluminates) while other Class C ashes containing similar amounts of ; elemental calcium are not (1). Fly ashes from modern power plants in ; Iowa contain significant amounts of calcium in their glassy phases, ; regardless of their cementitious properties. The present research ; was based on these findings and on the hyphothesis that: attack of ; the amorphous phase of high calcium fly ash could be initiated with ; trace additives, thus making calcium available for formation of ; useful calcium-silicate cements.
