Abstract

Concrete is a core material in infrastructure construction, yet its tendency to develop cracks significantly impacts structural durability and safety. Traditional repair methods are costly and often ineffective, making microbial self-healing technology a recent research hotspot due to its unique advantages. This technology utilizes metabolic products from specific microorganisms to repair concrete cracks, offering environmentally friendly features and long-lasting durability. This review comprehensively examines the causes of concrete crack formation, the strengths of microbial self-healing technology, applicable microbial strains, carrier materials, and current applications. It aims to provide references for advancing research and promoting the engineering adoption of microbial self-healing concrete, ultimately facilitating broader implementation of this innovative and eco-friendly technology in practical engineering projects.
