Performance Enhancement of Fine Fly Ash and Pond Ash Material in Self Compacted Concrete

Due to increase in the growth of industrial sectors the power requirement of the country is rapidly increasing. India depends on Thermal Power as its main source, thus there is increase in power requirement every year. Present scenario of our country shows 75 % of country’s total installed power generation is thermal of which coal-based generation is 90%. The coal reserves of the country are predominately of lower grades (average of 35% ash content), non-cooking and as a result more than 110 million MT coal ash is being generated every year. Ash generation may likely reach to 170 million MT by 2012. Use of coal brings huge amount of ash every year. Research related to new and innovative use of waste materials is being undertaken worldwide. Properties of materials include strength, hardness, density, resistance to corrosion, etc. Materials in industrial wastage has properties like unit weight, specific gravity, shrinkage, absorption, resistance to freezing, etc. The industrial waste material is a bye-product of construction industries and other industries and their wastes are fly ash, pond ash, marble dust, store dust, slag and many more. In this research study modifications in normal concrete materials such as cement aggregate and sand were carried out. Properties of concrete were replaced by fly ash and pond ash. The construction waste material which gives better performance in special concrete was identified. Fly ash and pond ash materials were selected which simultaneously replaces the cement and sand of the special concrete and better results were obtained related to the properties of concrete.
