Abstract:

Fly ash (FA)- is a waste by- product extracted by mechanical /electrostatic precipitator, obtained from coal fired power plants. India has some of the largest reserves of coal in the world. At present scenario, around 160 million-tons of fly-ash is produced which is nearly twice over the last decade. In India most of the thermal power plants are utilizing bituminous and sub-bituminous coal and produce large quantities of fly ash. High ash content (30% - 50%) coal contributes to these large volumes of fly ash. Fly-ash is used in various sectors like brick making, roads & embankments construction, cement manufacturing, agricultural uses, reclamation of low lying areas, mine filling, Ash Dyke Raisingetc .The unutilized huge quantity of fly ash has drawn the attention of researchers to explore new strategies for bulk utilization. Fly ash embankment is one of the thrust areas to consume fly ash in bulk .As in India current scenario of utilization of fly ash in roads and embankment is only 6%.The present paper represents the potential applications for fly ash as an embankment material.Fly ash possesses most of the important and favorable geotechnical characteristic for its usage as embankment fill.
