BACTERIA BASED SELF-HEALING CONCRETE :A REVIEW

Abstract

Concrete is one of the most commonly used building materials, and which is prone to cracking. The service life of concrete is significantly reduced due to these cracks. Replacement are High costs and difficulties in avoiding the cracks, various methods are in place to prevent crack formation such as filling in the gaps. It has been demonstrated current treatment methods of concrete are Chemical and polymer applications which they are a source of health and environmental issues, and they are only getting worse successful under some situations. As a result, environmentally sustainable treatment methods will be required in the near future. The potential for long-term, rapid, and active crack repair distinguishes the microbial self-healing method, which is also environmentally friendly. in addition, microbial self-healing Thanks to the effectiveness of this procedure, which out performs most treatment methods. Concrete compatibility and effective bonding capability assemblages. This paper gives an overview of the various microbial methods for producing calcium carbonate (CaCO3). Future challenges in microbial crack treatment are discussed, as well as recommendations for future research areas.
