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