Mortar repaired reinforced concrete structure

A repaired reinforced concrete structure comprising:

• 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 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 including at least approximately 1 percent by volume of reinforcing steel fibers, one or more polymers in a total polymer amount of approximately 1 weight % to approximately 3 weight percent, and a superplasticizer in an amount from approximately 0.03 weight % to approximately 0.05 weight % such that the reinforced repair mortar restores a strength of a repaired region to greater than or equal to approximately 100% of an original strength of a same region of concrete structure in an uncorroded state and wherein the reinforced ordinary Portland cement-based repair mortar exhibits an air permeability resistance of greater than 1000 seconds and wherein reinforced concrete structure does not accelerate the corrosion of the one or more reinforcing steel bars.
