: In India, coal is a major source of fuel for power generation. About 60% of power is produced using coal as fuel. Indian coal has a very high ash content resulting in huge quantity of ash generation in the coal based thermal power stations. Bottom ash is the coarse, granular, incombustible by-product of coal combustion that is collected from the bottom of furnaces. This ash is dark grey in colour, and is about the size of sand. In the year 2020, approximately 19.6 million tons of bottom ash was produced. Geotechnical engineering provides vast scope for utilization of bottom ash as a substitute to soil in embankments and subgrades. Knowledge of geotechnical characteristics of bottom ash helps to promote bulk utilization of bottom ash. Many successful case histories have been reported by many researchers on the utilization of bottom ash in various civil engineering applications like replacement of fine aggregate in cement and as fill/back fill materials. Bottom Ash is successfully used in the construction of embankments as a fill material (C. William hovel et al. (1990), as a partial replacement of cement (Mohd Sani, et. al., (2010)), In the present paper an attempt is made to study the suitability of bottom ash as fill / back fill material. many researchers are reveals the strength characteristics (ϕ and CBR value) of bottom ash and its suitability in civil engineering constructions. This paper mainly focusing compressibility characteristics (Cv & Cc) bottom ash. To study the compressibility characteristics of bottom ash, it was tested in one dimensional consolidometer and the coefficient of consolidation (Cv) under different consolidation
