replacement of sand by fly ash and bottom ash

Bottom ash forms up to 25 of the total ash while the fly ash forms the remaining 75 One of the most common uses for bottom ash is as structural fill Published literature shown that there is a strongly possibility of coal bottom ash being used as substitutereplacement of fine aggregate sand
