Abstract
Landfill liners are integral part of waste management for isolating the harmful wastes from surrounding environment. In the absence of impermeable natural soils, compacted mixture of expansive soil and sand have found wide applications as landfill liners. In this study, attempt was made to replace sand with thermal power plant by-product fly ash. Annual production of fly ash in India is approximately 170 million tons per annum out of which only 61% is being used in construction of road and embankments, production of cement, reclamation of low lying areas, agriculture, making bricks, tiles and others. There is limited literature on the utilization of waste product (fly ash) for waste management applications. The major objective of this research work is to explore the utility of waste fly ash in waste management. The study clearly demonstrates the utility of fly ash as a substitute of sand in the construction of liners.
