Abstract: With the development of the use of a biological healing cracks technique, to study building the microorganism healing agent into concrete to carry the point of concrete healing positively is of great practical significance.This paper reviewed some research achievements and progress of typical building the microorganism healing agent into concrete to inducing generating mineral salt healing cracks technique, discussed the existing problems and engineering application research prospect of healing cracks technique.Finally the main problems to solve built-in microbial self-healing material repair technology were pointed out.The review shows that: the self-healing materials and technology are still in the research stage of the lab, so it is really used less in the engineering, so it is necessary to seek other low-cost and low-requirement microbial carriers.
