Abstract
The microbial self-healing concrete has been a new technology to repair cracks, the former study showed that the precipitated CaCO3 could fill the cracks and reduce the permeability coefficient of cracks. On this basis, the impacts on resisting transmission of chloride were studied to evaluate the protective effects of microbial self-healing cracks, through multiple characterization methods such as electrochemical test, visual examination of cracks surface, weight-loss ratio of reinforcements and chloride ion content. Besides the method of electromigration was used to accelerate the transmission of chloride. The results show that the microbial self-healing cracks can indeed impede the transmission of chloride in cracks and have protective effects for reinforcements in the concrete.
