Fly Ash Concrete. Fly ash in concrete contributes to a stronger, more durable, and more chemical resistant concrete mix. The main benefit of fly ash for concrete is that it not only reduces the amount of non-durable calcium hydroxide lime, but in the process converts it into calcium silicate hydrate CSH, which is the strongest and most durable portion of the paste in concrete.
