Abstract
Concrete is widely used as a construction material in modern society with the growth in urbanization and industrialization and the demand for concrete is increasing day by day. Therefore, raw materials from natural resources are required in large quantities for concrete production. At the same time, a considerable quantity of industrial wastes mostly from thermal power plants is available in large quantity and the disposal of this material becomes a major issue. Fly ash generated in the power stations is consumed in the cement industry whereas the bottom ash is disposed in the open ground. Hence the bottom ash was used as a substitute for fine aggregate in concrete. This project work aims to study the performance of bond strength of concrete containing bottom ash as a partial substitute for fine aggregate with different water cement ratios of 0.37, 0.38, 0.45 and 0.57. The assessment involves determination of bond strength properties of concrete with 40% bottom ash as partial replacement. The bond strength is proposed to be evaluated as per IS: 2770. Compressive strength, Split tensile strength, flexure strength and bond strength curves were determined compared with concrete containing 0% bottom ash were studied of bottom ash concrete
