MORTAR REPAIRED REINFORCED CONCRETE STRUCTURE
A repaired reinforced concrete structure is provided which includes one or more reinforcing steel bars of cross-sectional area Ax, the one or more reinforcing steel bars having one or more corroded sections of cross-sectional area Ay, wherein Ay is greater than or equal to approximately 0.6 Ax. A reinforced ordinary Portland cement-based repair mortar is positioned directly on the one or more corroded sections of the one or more reinforcing steel bars without the addition of a lapped reinforcing steel bar. The reinforced repair mortar includes at least approximately 1 percent by volume of reinforcing steel fibers such that the reinforced repair mortar restores a strength of a repaired region to greater than approximately 100% of an original strength of the concrete structure in an uncorroded state. The repaired reinforced concrete structure is highly durable, as the repair mortar exhibits an air permeability resistance of greater than 1000 seconds.
