The research described in this contribution considers the ability of a coupled finite element model to simulate cracking and healing behaviour in cementitious samples for a range of enhanced autogenic and autonomic healing systems. The work is an enhancement of a recent coupled 3D finite element model which was first developed for simulating vascular self-healing systems with cyanoacrylate as the healing agent1-4. The model employs a cohesive zone constitutive model for simulating the damage-healing behaviour of an embedded interface within 3D continuum elements. Fluid flow is simulated using a mass balance equation and Darcy’s law. Healing is computed via a generalised curing front model that simulates the accumulation of healed material within a crack. The research reported here demonstrates that the curing front model can be calibrated and applied to predict healing in vascular systems with sodium silicate as the healing agent, autogenous healing in a cementitious specimen with and without crystalline admixtures, as well as healing derived from Microbially Induced Calcium Carbonate Precipitation. A set of simulations are presented that demonstrate the ability of the model to simulate the mechanical and transport behaviour observed in experiments for all these self-healing systems with good accuracy.
