Effect of Fly Ash on Setting Time
Fly ash doesn't chemically retard setting. But many times fly ash is used in concrete as a cement replacement in combination with a water reducer. These concretes may set more slowly than a straight cement mix would. If fly ash is not being used as a cement replacement, but is added just to increase fines, it won't retard setting.
