Self-Healing Concrete: A Review of New Era in Advance Construction Concrete and Future Prospects

Cracks in concrete buildings can make them last much less long because they let outside elements damage the support, which in turn damages the concrete. Cracks in concrete can find and fix themselves with microbial weathering technology. However, this technology hurts concrete during freeze-thaw cycles because of the water that is present, especially in cold places. A lot of research has been done on the progress made in making self-healing devices for concrete. This review paper looks at self-healing bacterial concrete systems, a new type of material that can make concrete buildings last longer and be more durable. The article talks about how bacteria help the body heal, including how bacteria make calcium carbonate to fill in cracks in the concrete substrate. The review also talks about how the technology could be used and the problems that might come up when it is scaled up in real-world building projects. The review points out the study’s flaws, hopes for the future, and important areas for further research.
