FLY ASH CONCRETE WHAT ARE THE REASONS FOR ADDING FLY

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

Effect of Fly Ash on Durability of Concrete

Fly ash concrete with low abrasion resistant might be expected unless the concrete is adequately and thoroughly curried. It is demonstrated that, concrete with ASTM class F fly ash provide better abrasion resistance compare with those contained ASTM class C or not fly ash content. Concrete is likely to be eroded when water flow over its surfaces.
