The use of bacteria-based self-healing concrete has gained attention in recent years due to its potential to improve the durability and sustainability of concrete structures. This paper provides an overview of the research conducted on the self-healing properties of bacteria-based bio-concrete. The paper discusses the mechanism of bacterial self-healing in concrete, the types of bacteria used in self-healing concrete, and the methods used to introduce bacteria into the concrete. The paper also reviews comparative studies that evaluate the mechanical properties and durability of selfhealing bacterial concrete compared to traditional concrete. The results of these studies demonstrate that the use of bacteria in concrete can improve the self-healing capacity of the material, leading to better mechanical properties and a higher resistance to cracking and freeze-thaw damage. Furthermore, the paper discusses the potential environmental and economic benefits of using self-healing bacterial concrete. The self-healing capacity of the concrete can reduce the need for costly repairs and maintenance of concrete structures, resulting in lower costs and a reduced environmental impact associated with concrete production. Additionally, the use of waste materials as nutrient sources for bacteria can promote the circular economy and contribute to sustainable development. Overall, this paper highlights the promising potential of self-healing bacterial concrete to improve the durability, sustainability, and economic viability of concrete structures.
