  Fly ash  is a fine powder that is a byproduct of burning pulverized  coal  in electric generation power plants.   Fly ash  is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water.  When mixed with lime and water,  fly ash  forms a compound similar to Portland cement.
