Abstract: A method of batch-casting high-fluidity high performance concrete and low-fluidity high performance concrete, wherein the method is capable of batch-casting high-fluidity high performance concrete for forming a girder portion of a bridge and low-fluidity high performance concrete for forming a deck plate portion of the bridge by using a concrete casting apparatus. Accordingly, the construction cost can be reduced and the construction period can be shortened. In addition, because a cold joint does not occur, durability can be improved, and thus the life of the bridge can be increased.

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.
