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.
