Zusammenfassung:PROBLEM TO BE SOLVED: To provide a concrete segment which can secure a necessary strength if the thickness of the segment is made thinner and also reduce its costs compared with the case of using a steel segment.SOLUTION: In a concrete segment 10, lattice-like reinforcements 20 are buried in the concrete so as to constitute a single reinforcement and reinforcing fibers 30 are mixed in the concrete. Preferably, steel fibers are used as the reinforcing fibers 30.
