Abstract
A concrete structure includes a continuous fiber-reinforced polymer material arranged as a main reinforcing material or a tendon. A short fiber reinforcing material consisting of an organic fiber is mixed in 0.5% or more with respect to an entire volume. The continuous fiber-reinforced polymer material is shaped like a rod or a stranded wire. A ratio Lf/Gm between a fiber length Lf of the organic fiber of the short fiber reinforcing material and a maximum aggregate diameter Gm of a concrete composition is 1.2 to 3.7, and an aspect ratio Lf/De, in which De is an equivalent diameter that is a cross-sectional area of the organic fiber converted into a circle diameter, is 30 to 69.
