Using Fly Ash in Concrete Precast concrete

May 08, 2010 · Fly ash is a pozzolan, and it reacts with calcium hydroxide and water. So for fly ash to begin its cementitious reactions, it first needs cement and water to react and create calcium hydroxide. The fly ash needs to wait for calcium hydroxide to become available, so this causes a slight delay in early strength development.
