Abstract:
During World War II, concrete for military bases in the Gilbert, Marshall, Hawaiian, and other islands in the North Pacific Ocean was often made with coral aggregates and seawater. Post-war reconstruction and nuclear testing programs conducted by the Atomic Energy Commission at two Pacific atolls also used concretes made with coral aggregates and seawater. This paper examines the long-term strength of coral aggregate and seawater concrete and the durability of three reinforced concrete structures that used this type of concrete.
