    Microbial induced calcium carbonate deposition(MICP) self-healing technology is an environmental friendly and long-term feasible repair method, which has attracted much attention in the field of concrete crack repair. Based on the research in recent years, this paper summarizes the deposition mechanism of calcium carbonate induced by different kinds of microbial, and compares and analyzes the differences of microbial carrier materials currently used. It is recommended to consider the effects of biocompatibility, immobilization ability, repair effect and other factors when selecting microbial carrier materials. Secondly, the characterization methods of microbial self-healing concrete are summarized, and the crack repair effect is comprehensively evaluated from the aspects of compressive strength recovery rate, crack surface healing rate, concrete durability and microscopic analysis. Finally, combined with the research progress of microbial self-healing concrete, suggestions for future research and development are given.
