Fly Ash is a product or furnace slag received form metal factories and power plants by burning or combustion of coal as fuel.
The maximum percentage of fly ash or 15% by weight of cement shall be replaced by fly ash.
#less percentage does not affect any properties of concrete or cement
#more fly ash reduces the strength of concrete and durability of concrete.
