Abstract
Concrete crack issues have always been the focus of attention in the field of civil engineering due to their direct impact on structural stability and durability. While some traditional repair methods are effective, they also possess numerous limitations. In contrast, microbial repair technology, apart from enhancing structural bearing capacity and durability, boasts environmental-friendly characteristics. This paper reviews recent research on microbial-based concrete crack repair, analyzing key aspects such as microbial species, repair mechanisms, methods, influencing factors, and characterization techniques. The aim is to provide new perspectives and ideas for future research.
Keywords: Concrete cracks, microorganisms, repair mechanism, repair methods
