摘要：

The development of an innovative self-healing technique based on microbial mediated formed calcium carbonate precipitation is promising. The method is to pre-incorporate special bacteria and substrate inside the concrete matrix to heal cracks the moment they appear, indicating that the concrete obtained a self-healing behavior. The self-healing efficiency based on the bacterially induced precipitation technique depends on bacteria strain, substrate types and concrete cracks size. Besides, there are some other factors related to healing efficiency, such as the quantity of living bacteria inside concrete, curing condition (water or medium) and curing ages, which all affect the self-healing efficiency. The assessment methods for healing efficiency using the bacterially induced calcium carbonate precipitation technique were carried out by various methods and the healing efficiency was examined. This paper reviewed the self-healing mechanism based on different bacteria strain, techniques utilized to characterize healing efficiency, the performance after cracks healing by bacterially induced CaCO3 precipitation and factors affected healing efficiency.
