Analysis and Development of Coal Bottom Ash Used for Embankment Filling

Abstract

Bottom ash is one of the coal combustion byproducts which is collected at the bottom of the furnace of coal fired thermal power plant which is the main source of production of coal ashes. In this investigation bottom ash taken from Vindhyachal thermal power plant, NTPC Singrauli have been used. Different laboratory tests pertaining to Geotechnical and highway material characterization has been made and the results have been compared with natural soil. A work additionally has been made to utilize balance out the low strength, leftover soil as far as expanding its solidarity and California bearing proportion esteems. The current work centers to portray the generally accessible coal bottom ash in the geotechnical applications and to discover the pertinence of such material as fill in Geotechnical designs, for example, dike and other comparable constructions and so on. In the present study, characterization of Coal Bottom ash to be used as a fill and embankment material and also used as a pavement material in road construction. Nonetheless, it can possibly be utilized as another structural designing material for filling and dike just as asphalt material for street development.
