Economical Design of Ash Bund for Disposal of Wonder Material- Fly Ash

Abstract

Fly ash is waste by product generated from a thermal power plant in huge quantity and its disposal is a majorproblem. As on today it is being disposed of either by dumping in open land, by refilling in low lying areas ordischarging water mix slurry form in impounding pond, river or sea. But in all of such methods it has a negativeimpact on environment.[1][3][7] Realizing these negative effects of fly ash on land and water; Government ofIndia and Government of Maharashtra, issued a notification directing all fly ash producer to prepare an actionplan to use fly ash fully. Consumption of electricity is indexing of developing country. Major source ofelectricity generation is thermal power plants and other resources are very poor in India. India is one of thefastest growing and developing country; generation of fly ash as waste material is increasing every year due toincreased demand of electricity. But it is unfortunate that still percentage utilisation of fly ash in India is verylow and most of the fly ash has to be disposed off for storage.[8] Keeping this in mind an effort is made byauthors to design bund for disposal of wonder material fly ash using locally available Black cotton soil ashearting material and murum as casing material for initially built minimum required height fly ash bund andafterwards height of bund is successively increased by using stored fly ash as hearting material and murum ascasing material in bund. This is the safe, economical and eco friendly storage of disposed fly ash.
