• In conventional underwater coal ash disposal, the major concern is to increase the disposal capacity by increasing the density. Underwater placement of coal ash slurry is thought to be one method to achieve this. The properties of the slurry and its density compared to the conventional disposal method, however, have not been studied. In this paper, the properties of a new high density slurry, the density of which is 96% of the maximum dry density, are shown from results obtained through laboratory tests. Since the density decrease during underwater placement is less than 4%, this slurry is expected to dispose of coal ash at 92% of the maximum dry density, even underwater. That corresponds to the same density as the field compaction, and 159% of the conventional disposal. The advantage of the new slurry method with regards to strength suggests new possibilities in the utilization of coal ash for stable fills.
