ENVIRONMENTAL ASPECTS OF COMPACTED MIXTURES OF FLY ASH AND WASTEWATER SLUDGE

The paper reports on a study to determine whether the resulting compacted mixtures would be physically suitable for use in highway embankments and other structural fills; and to determine the extent of adverse environmental effects, especially leaching of potentially harmful trace elements. The first objective was evaluated on the basis of unconfined compressive strength and permeability for samples compacted near the optimum moisture content. Evaluation of the second objective was based on analysis of simulated leachate. Measurements of the extent of biological degradation of organics in the sludge aided evaluation of both objectives.
