Although I am in steel construction, I attend construction coordination
meeting regularly. The question came up regarding the addition of fly ash
and why it was not allowed on this particular project. The Owners Rep. had
had a bad experience with it and would not allow it and the Structural
Design Engineer said it was company policy not to allow it. I can
understand the Owners rep comment, but the Engineers was interesting. My
point before I ramble much farther and expose my ignorance is this.
Does the addition of fly ash provide an improved Concrete, and in
Freeze thaw breakdown resistance
Alkalinity improvement (reduce carbonation)
I look forward to the final word on this.
