Leaching Studies on ASTM Type F Fly Ashes by an Accelerated Process Method



Among the various uses for fly ash, geotechnical application is one that offers scope for large-scale utilization. Due to its low unit weight, good frictional properties, and non-plastic nature, fly ash can be used effectively as a fill material in low-lying areas, as a backfill material, as an embankment material, etc. However, the possibility of toxic metals being leached out, leading to surface and/or groundwater contamination, has to be examined. This paper presents such an investigation carried out on two Indian fly ashes. The studies indicate that the pH of the solution plays an important role in the leaching behavior of fly ashes.
