Abstract: Disclosed is a concrete repair composition including an aggregate, a binder, and a fiber reinforcement, wherein the fiber reinforcement includes jute fiber having an average thickness of 65 to 75 ?m and an average length of 3 to 6 mm. The jute fiber used for reinforcement has excellent dispersion and bonding when mixing. Also, the jute fiber has high moisture holding capacity, and thus the concrete repair composition can retain water therein during curing, thereby preventing a false-set problem caused by rapid hardening of cement.
