Title:Studies On The Leachate Characteristics Of Compacted Fly Ash Bed Treated With Lime Column
Author Name:S.P. Singh and S. Sangita
Synopsis:
This paper delineates the effect of lime column on the leachate characteristics of compacted fly ash bed. In the present experimental investigation, large scale laboratory model of compacted fly ash bed was prepared by adopting maximum dry density and optimum moisture content condition and a lime column was installed at the center in order to facilitate in-situ stabilization of fly ash. The samples were collected from different radial distances as well as depths after 7, 30, 90 and 180 days of curing periods and subjected to different tests such as pH, leachate analysis and hydraulic conductivity. From the test results, it was observed that lime column treatment is an effective means of reducing the permeability and concentration of metals in the leachate emanating from compacted fly ash bed.
