PROBLEM TO BE SOLVED: To provide a fiber-reinforced concrete less likely to generate crack, having crack staying at local even with crack even when using sea water as milling water, i.e. less likely to connect cracks each other or largely expanding the crack.SOLUTION: There is provided a fiber-reinforced concrete containing cement, an aggregate and alkali resistant organic fiber having Young modulus of 3 to 100 GPa with the content of the alkali resistant organic fiber of 0.1 to 5 vol.% to the concrete volume and manufactured by milling with sea water.SELECTED DRAWING: None |
