<p>Microbially Induced Calcium Carbonate Precipitation (MICP) has demonstrated high potential to enhance the self-healing of concrete cracks under complex loading and environmental conditions. Nevertheless, it remains difficult to quantitatively predict and model the self-healing behavior of various crack geometries. The Box-Lucas and Boltzmann models are used in this work to study the self-healing properties of different types of cracks in concrete. The results of an experimental study using a cyclic injection technique are modeled and examined to measure area-repair rates, reductions in water seepage, and changes in healing rates across different crack structures. Under optimal conditions, as the results have shown, wide and diagonal cracks can achieve water-seepage reduction and healing rates of about 70% to 80%, and the repair rate of micro-cracks can be almost 100%. Greater tortuosity and surface roughness of cracks significantly increase the rate of calcium carbonate deposition and self-healing. Moreover, the area repair rate of vertical cracks shows a linear positive correlation with changes in water ingress rate, whereas the diagonal cracks show a nonlinear positive correlation. These quantitative results provide a solid foundation for predicting the multi-type of crack self-healing behavior and for developing a complete theory of microbial-driven crack repair under multifactorial coupling conditions.</p>
