  Study on effective utilization of coal ash in the conservation …

  2023420 · The maximum dry unit weight and optimum moisture content of the pond ash were found to be 10.74 kN/m 3 and 33.5%, respectively. Figure 3 depicts the compaction curve of the pond ash. Pond ash possesses less unit weight than that of the soil of the same gradation because of less specific gravity.
