Damage and permeability in quasi-brittle materials: from diffuse to localized properties

Abstract : Transport properties of concrete, like permeability or diffusivity, are particularly important in the case of structures for which tightness is important, for instance for pre-stressed concrete containment vessels in nuclear power plants. For such sensitive nuclear vessels, tightness to gas is critical during their service life, where concrete remains at most micro-cracked, but also upon minor accidents, when macro-cracks may appear locally. Thus, it is important to provide relationships between the amount of cracking and damage in concrete and its intrinsic permeability.
