Microbial self-healing in concrete: A comprehensive exploration of bacterial viability, implementation techniques, and mechanical properties

Cracks in concrete structures can significantly decrease their lifespan by exposing reinforcement to outside environment, leading to concrete degradation. To address this issue, self-healing techniques have been developed, including biomineralization-based-self healing, where bacteria are employed to initiate microbially induced calcium precipitate (MICP), promoting the healing of cracks. This article explores the extreme environmental conditions including pH and temperature which can reduce sustainability and self-healing potential of bacteria. Furthermore, it explores the implementation techniques of using bacteria in concrete aimed at mitigating the adverse effects of the concrete environment on bacteria,…
