Influence of bottom ash as a sand replacement material on durability of self-compacting concrete exposed to seawater

Concrete strength and durability performance under marine environment have been considered as challenging issue for many decades because seawater contains aggressive salts and it could affect the service life of concrete structure that is expected for the marine environment, such as offshore, harbou...
