PROBLEM TO BE SOLVED: To provide a method for repairing concrete, which prevents a gap and a crack from being made even after repair. SOLUTION: The method for repairing the concrete includes a process in which after removal of a deteriorated concrete part by means of a water jet, a part, from which the deteriorated concrete is removed, is filled with shrinkage- compensating mortar having a shrinkage factor of 500 microstrains or less, preferably, of 300 microstrains or less in a week and 500 microstrains or less in four weeks, by a measurement based on ASTM(American Society for Testing and materials) 157. The shrinkage-compensating mortar contains synthetic fibers of 0.1-20 wt.%. Preferably, polyester fibers are used as the synthetic fibers. |
