Insight into the role of microbial calcium carbonate and the factors involved in self-healing concrete

Microbial calcium carbonate has been widely investigated to self-heal concrete cracks. However, the issue revolving around the efficacy of crack self-healing remains important. In particular, existing works are still lacking of a better understanding of the factors affecting the fundamental reactions involved as well as bacterial growth in harsh condition such as concrete. In this study, a comprehensive investigation was conducted to explore the...
