Abstract
A computational assessment of water and salt transport parameters describing the coupled moisture and chloride transport in porous media is presented in this paper. The experimentally determined moisture profiles, chloride concentration profiles and chloride binding isotherm are subjected to inverse analysis where three different modes of salt solution transport are assumed. On the basis of this analysis, moisture dependent moisture diffusivity and salt concentration dependent chloride diffusion coefficient are calculated. The obtained results can find use in computational modelling of salt transport in porous building materials which is currently a very important topic, particularly from the point of view of durability of building materials and service life of building structures exposed to salt attack.
