| 要旨 | Although concrete is one of the most extensive building material, it cannot prevent cracking caused before hardening or after hardening periods. It is necessary to understand the origin of the cracks and how to repair them efficiently. Hence, self-healing concrete using bacterial mineralization can be a core solution for a combination of self-healing techniques. In this study, we aim to figure out the ability to repair the cracks with 1 mm-width by using Bacillus subtilis natto bacteria immobilized in lightweight aggregate. Crack healing was determined through the strength recovery and image analysis method. |
