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
