摘要

We mixed Bacillus subtilis and brewing yeast to prepare composite microbial self-healing materials, and studied the self-healing effect of composite microorganisms in mortar cracks of different widths and cracking ages. The experimental results show that the performance and self-healing effect of composite microorganisms are significantly better than those of single microorganisms. For cracks with widths of 0.2–0.4 mm, the repair effect of the composite microorganisms at 28 days is 42.7% and 71.2% higher than that of pure Bacillus and pure yeast, respectively. The repairing rate of the area with the widths of the cracks of 0.2–0.4, 0.4–0.6, and 0.6–0.8 mm are 100%, 77.3%, and 53.4%, respectively. The area repair rates corresponding to cracking ages of 56, 90, and 180 days are 73.3%, 55.4%, and 30.8%, respectively.
