| Outline of Final Research Achievements |
The author investigated in order to enhance the adhesive performance of concrete-repair interface by means of fracture toughness test and FEM analysis. The specimen with steel fiber and aggregate marked the maximum strength showing 4.84MPa with the repair-fracture ratio reaching 81%, which is 79% of the strength of matrix and 68% of the strength of repair. The maximum repair-fracture ratio reached 96.1%. Then the purpose of the study for achieving high adhesive performance in the interface was duly attained with fracturing the repair avoiding the interface-fracture. Also the author resorted to FEM analysis for verifying the experimental results.
