Abstract

The coal-fired thermal power plants are the main source of coal bottom ash. Coal Bottom Ash is used as a replacement of both sand and cement depending on the size of bottom ash. The present study will provide a better understanding of the mechanical and durability properties of concrete in which cement is partially replaced with bottom ash. The present thesis would contribute to the efforts being made in the field of concrete technology towards the development of concretes possessing good strength. Based on the study, valuable advice will be given to concrete structures. In the present experimental study, the various strength properties like a compressive strength of concrete and also durability properties like Acid attack test on both ordinary concrete and coal bottom ash Concrete, best coal bottom ash concrete mix is carried out and compared with an ordinary concrete mix for economic and ecological study. In this study different percentage of ordinary and grinded coal bottom ash is used. It was found that with the increase in the amount of coal bottom ash, standard consistency, initial and final setting time increases at the same time workability of concrete decreases. It was also found that initial day’s strength is less for bottom ash concrete compare to control mix, but as the age increases, they show good improvement in strength due to a pozzolanic reaction. Optimum dosage is observed to be 15% GBA which shows more strength compared to the control mix at 56 days. It was found that with the increase in an amount of bottom ash resistance to acid attack increases. GBA shows more resistance to acid attack compared to OBA. With the increase in the amount of bottom ash. It was also found that at optimum dosage i.e at 15% replacement of cement with GBA it is also economical and also amount of CO2 Emitted is also decreasing that means it is also environmentally friendly compared to control mix.
