Self-healing capsules in early-age cementitious composites: A deterministic-probabilistic multi-scale approach

Capsules for healing early-age concrete cracks should possess multi-functional properties to ensure shell rupture and release of healing agents rather than debonding from the cementitious matrix when intercepting a crack. A deterministic-probabilistic multi-scale model is developed to determine the probability of capsule rupture versus interfacial debonding induced by early age volume change. A micromechanical model along with a probabilistic …
