Self-healing cementitious materials could greatly improve the durability properties of concrete structures relative to those constructed with conventional cementitious composites. However, there is a need to understand better the healing processes, to predict accurately experimental behaviour and to determine the impact on mechanical properties. Micromechanical modelling, with a two-phase Eshelby inclusion solution, is chosen as a suitable framework within which to explore such a response in cementitious materials. A constitutive material model is described, consideration is given to a self-healing model framework and how the mechanical strength recovery of a micro-cracked material can be simulated with a simplified volumetric micromechanical model.
