Abstract Bacteria-based self-healing concrete has emerged as a promising solution for enhancing structural durability by autonomously repairing cracks. However, the underlying transport mechanisms of healing agents and efficiency mineral precipitation remain inadequately modelled. This study presents finite element modelling (FEM) approach to simulate diffusion reaction kinetics bacterial in microstructures. X-ray micro-computed tomography (Micro-CT) meshes were utilized accurately represent crack pore geometries, while diffusion-reaction equation governing calcium carbonate (CaCO 3 ) was numerically solved using FEniCS. Key input parameters, including coefficients, rates, efficiencies, extracted from literature ensure model validation. Simulations reveal that agent concentration follows nonlinear pattern, with influenced geometry metabolic activity. Heatmaps contour plots highlight dispersion, time-dependent analysis indicates 65.5% closure under optimal conditions. The proposed effectively replicates experimental trends, demonstrating its applicability predicting performance realistic provides computational framework can be extended optimize bacteria encapsulation strategies, kinetics, long-term assessments concrete.
