AN EXPERIMENTAL STUDY ON STRENGTH PERFORMANCE OF CONCRETE(M20) WITH PARTIAL REPLACEMENT OF FINE AGGREGATE WITH POND ASH

Power consumption is increasing day by day for utilization. Power is generated from different power plants such as Thermal power plants, hydraulic power plants, solar power plants and etc…, A major portion of the power is generated from thermal power plants. The main source of power generation in thermal power plants is Coal. When combustion of Coal occurs in the power plant, Ash is produced as a by-product which is an Industrial waste. This ash is of different forms such as Fly ash, Bottom ash and Pond ash. A major problem arises on the disposal of this industrial waste. As days go on more coal is utilized and more ash is made ready for the disposal, so this becomes a serious problem. These industrial wastes are to be utilized in different fields such as construction and etc…, to minimize its disposal problems. In this study Pond ash is utilized as a partial substitute of fine aggregate (Natural sand) in concrete. The properties of pond ash were determined and compared to the properties of sand. Pond ash is added in the concrete by replacing 10%, 20% and 30% of fine aggregate to determine the strength properties. The Casting of cubes and cylinders are done to determine the compressive strength and split tensile strength respectively, for 7, 28 and 90 days of curing. Optimum strength has been obtained at 20% replacement of fine aggregate by pond ash in cement concrete.
