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.
