Effect of Fly Ash on Setting Time Concrete Construction ...

Oct 01, 1992  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.

Jun 27, 2017  An equivalent or greater weight of fly ash is substituted for the cement removed. The substitution ratio for fly ash to portland cement is typically 1:1 to 1.5:1. A mix design should be evaluated with varying percentages of fly ash. Time versus strength curves can be plotted for each condition.

Fly Ash Concrete - an overview ScienceDirect Topics

For both fly ashes, a 5% calcium hydroxide addition by mass restored the initial and final setting times to be nearly identical to those of the control cement paste (i.e., no fly ash). For the rapid set cement, while a 5% addition was adequate for the Class F fly ash mixture, a 10% addition was required for the Class C fly ash.
