Abstract
The present paper discusses the major corrosion mechanisms of concrete subjected to an aggressive environment. The majority of these deleterious reactions involves the transport of gases, liquids or ions through the porous cement paste matrix, and relationships are given between the permeability of concretes for these species and the observed corrosion rates. In many cases, transport parameters of concretes such as diffusion coefficients, coefficients for gas and water permeability, or the capillary suction rate may represent a characteristic parameter to describe the corrosion rate. However, corrosion mechanisms also exist which do not depend on the transport of species or which require additional information on the concrete composition. In these cases, transport parameters alone are insufficient to characterize the corrosion resistance of a given concrete.
