Abstract - An intriguing new technique that can assist in self-repairing concrete cracks is bacteria-based self-healing concrete. Special bacteria in this concrete produce a substance that fills and plugs holes when they get pushed by nutrients and water. strengthening and extending the concrete's lifespan. Concrete is infused with certain types of bacteria, such as Bacillus subtilis, and how they are maintained to remain active throughout time. According to the results, this bacteria- based polymer can strengthen, prevent water damage, and slow the spread of cracks. This technique offers the building sector an environmentally friendly alternative by increasing the durability of concrete structures and reducing maintenance expenses. The development of a bio-concrete with far better self-healing qualities could lead to the creation of a new kind of long-lasting, recycled concrete with a variety of possible uses.
