Abstract |
Concrete is widely used in structures for its cost-effectiveness, strength, and durability. However, concrete structures experience deterioration such as cracks or spalling, requiring sectional repair works. This study investigated repair performance based on different deterioration removal methods, application of saturated surface dry conditions, coarse aggregate inclusion in the repair material, and curing agent application. Field experiments were conducted, and performance was evaluated through bond strength measurements. The results indicated that the use of water jetting for deterioration removal, utilizing polymer cement concrete as the repair material, and the application of a curing agent each contributed to improved bond strength, indicating enhanced repair performance.
