Abstract: Provided are a marine concrete composition using dechlorination microorganisms capable of easily removing chlorine generated by seawater through an electrical method by allowing electrons emitted from electricity-generating microorganisms to flow through steel fibers incorporated into ultra-high-performance concrete (UHPC) or high-performance fiber reinforced concrete (HPFRCC) through a dechlorination microbial capsule carrier and capable of self-healing concrete crack sites through a self-healing microbial capsule carrier and is also capable of fundamentally solving the problem of reduced durability against salt damage of ultra-high-performance concrete or high-performance fiber reinforced concrete for application in marine construction environments through a dechlorination microbial capsule carrier, and a method for constructing a marine concrete structure using the same.
