Introduction: For concrete structures, the presence of cracks is a very common phenomenon.
But some may cause a decrease in structural load-bearing capacity and reliability; Some may not have a significant impact on the bearing capacity, but they may cause issues such as detachment of concrete protective layer and accelerated corrosion of steel bars, which can reduce the durability of the structure and pose a greater risk to its safety.
Therefore, how to evaluate, identify, and repair cracks in concrete structures is of great significance for the use and maintenance of the structure.
