Fly ash is the fine powder produced as a product from the combustion of pulverized coal. When the pulverized coal is ignited in the combustion chamber, the carbon and volatile materials are burned off. However, some of the mineral impurities of clay, shale, feldspars, etc., are fused in suspension and carried out of the combustion chamber in the exhaust gases. As the exhaust gases cool, the fused materials solidify into spherical glassy particles called Fly Ash. The disposal of fly ash is one of the major issues as dumping of fly ash as a waste material may cause severe environmental problems. Therefore, the utilization of fly ash as an admixture in concrete instead of dumping it as a waste material can have great beneficial effects of lowering the water demand of concrete for similar workability, reduced bleeding and lowering evolution of heat. This paper deals with an experimental study on the properties of concrete containing fly ash. Both strength and durability tests were conducted on fly ash concrete. The cube compressive, split tensile and flexural tests of fly ash concrete were conducted in this study to determine the strength parameters. And Acid Resistance, Saturated Water Absorption and Porosity tests were conducted to determine the durability behaviour of fly ash concrete. The cement was replaced by10, 20, 30, 40 and 50 percentages of fly ash obtained from nearby thermal power station. Fly ash replacement up to 30 percent in concrete has shown good improvement in strength parameters.
