The paper critically examines the development and application of self-healing concrete, particularly focusing on its capacity to autonomously repair cracks and microfractures, thereby enhancing structural durability and reducing environmental impact. The review highlights the application of microbial methods, especially the use of bacteria such as Bacillus sp., in facilitating the repair process in an environmentally friendly manner. It explores the mechanisms of self-healing concrete, its sustainability benefits including prolonged lifespan of structures, reduced maintenance requirements, and decreased carbon emissions. However, the paper also addresses the challenges and limitations associated with the technology, such as the efficacy of bacteria over long-term applications and cost considerations. Furthermore, the manuscript provides insights into practical applications and case studies of self-healing concrete, showcasing its effectiveness in real-world scenarios. The incorporation of Life Cycle Assessment (LCA) in evaluating self-healing concrete is discussed, offering a comprehensive understanding of its environmental impact throughout its life cycle. Despite the challenges, the potential benefits of self-healing concrete are emphasized, positioning it as a promising avenue for sustainable construction practices in the context of growing global demand for concrete and the need for environmentally conscious solutions.}, number={1}, publisher={Cankiri Karatekin University}
