This study was conducted to develop self-repairing ability for concrete so that inspection could be available even in the event of minute cracks, for more economic concrete structure maintenance and longevity. This is a basic attempt to develop self-repairing concrete using the biochemical reaction of bacteria through an innovative method. In this study, the characteristics
and problems posed by self-repairing concrete as proposed in international scientific journals were examined, and the potential of new concrete reformation and performance improvement using bio-mineralization was explored. Bio-mineralization, which is an action of creating bio-minerals using an organism, was proposed. A new concept of bacteria such as Sporosarcina pasteurii using bio-mineralization that precipitates calcium carbonate, as well as the possibility of mechanical performance and durability of concrete and repair of cracks, was introduced. Directions for further study through basic experiments and developmental feasibility of self-repairing concrete were also presented.
