Bottom Ash is a new waste material and abundantly available. It is a solid residue which falls into furnace bottom in modern large thermal power plants and constitutes about 20% of total ash content of the coal fed in the boilers. Direct use of this material with a large quantity, will provide a solution to dispose of this material, and the possibility as alternative materials in construction. The main objective of this research is to study the behavior of concrete mix which comprises of partial replacement of fine aggregates with bottom ash against plain concrete. The study was carried out using coal bottom ash as a partial replacement with fine aggregates in the concrete mix by 20%, 30%, 40%, and 50% by weight. The various strength properties studied consist of compressive strength, flexural strength and splitting tensile strength. The results shows that the compressive strength, split tensile strength and flexural strength decreased as the percentage of replacement of bottom ash increased as compared to plain concrete. It was observed that up to 20% replacement the results of compressive test, flexural test and split tensile test are approximately same as that of the controlled concrete.
