Bacterial-based self-healing concrete is comparatively a new technology, so it is essential to collect more results in real-world conditions before implemented on larger-scale applications. This article reviews the types of bacteria used in concrete and how they are used as healing agents. This article also briefly describes the various properties of concrete, which vary with the addition of bacteria. Micro-cracks are inherently present in concrete, which causes the concrete to degrade, causing harmful substances to enter the concrete, resulting in structural deterioration. To overcome these situations, self-healing techniques are employed. Calcite and calcium sources are produced by the addition of bacteria that forms precipitation of calcite in concrete. Bio-mineralization technology provides promising results for sealing micro cracks in concrete. The freshly formed micro cracks can be sealed by a permanent hydration process in the concrete. In order to improve the pore structure in concrete, the bacterial concentration was optimized to obtain better results. At last, comparison of compressive strength and water absorption is presented.
