Bond of repair materials to deteriorated RC structures is of importance in the application of patch repair materials. Compression-shear and tension-shear bond tests were carried out to obtain bond failure envelope in consideration of every stress condition between repair materials and substrate. In the case of the compression-shear bond test, bond strength is quite affected by strength of base materials (repair material or substrate), because rough surface of substrate heighten internal friction angle and strength of interface between repair material and substrate become higher than those of base materials. However, in the tension-shear bond test, polymer cement ratio (P/C), water absorption and roughness of substrates are ultimate trigger for bond strength. Consequently, the guideline for selecting appropriate repair materials was proposed on the basis of the test results.
