A Comprehensive Review of Self-Healing Concrete: Mechanisms, Benefits, and Future Prospects in Construction

Self-healing concrete is one of the most innovative advancements in the construction industry, introduced with the aim of increasing durability, reducing maintenance costs, and improving structural performance. This type of concrete utilizes natural or artificial mechanisms to autonomously repair micro-cracks formed within its structure. Various techniques such as the use of bacteria, capsules containing healing agents, and smart fibers have been developed to enable this self-repairing capability. This paper reviews the fundamental concepts of self-healing concrete, its development methods, advantages, limitations, and practical applications. The purpose of this study is to provide a comprehensive overview of the current state of research in this field and to analyze the future potential of self-healing concrete in construction projects.
