Abstract
The development of fishing grounds has been proceeding by creating artificially up-welling currents through the construction of large sea mounds. While the creation of artificial upwelling currents requires large sea mound, use of fly ash has been studied from a viewpoint of effective resource utilization. Such studies have resulted in the development of high Volume Fly-Ash Concrete using a large amount of fly ash. This paper describes the High Volume Fly-Ash Concrete and the development of Mounds Coastal Fishing Grounds.
