Cementitious composites are inevitably to be cracked in engineering structures due to their inherent brittleness and low tensile strength. The capsule-based self-repairing system provides a feasible method for repairing and delaying the potential damage of cement-based material matrix. The occurring, spreading and fracturing process of micro-cracks and microcapsules fracture behavior in the self-repairing model material were simulated by an extended finite element method, and the hitting probability was validated. Meanwhile, the effective elastic modulus of self-repairing cementitious materials before and after repairing by spherical/spherical microcapsules with different contents was calculated via composite materials theory, and the repairing efficiency was characterized.
