Many of the causes of the occurrence of pathologies in reinforced concrete structures are linked to the transport of different substances through the pores and fissures of the mortar cover layer and the concrete itself. This transport is influenced by environmental factors and the properties of the porous media. This paper deals with the application of geotechnical techniques to obtain chloride transportation parameters in mortar samples. The filter paper technique was used in order to obtain the water retention curves, and column tests were performed to obtain parameters such as retard (attenuation) factor, diffusion and mechanical dispersion coefficients and permeability. These techniques proved to be useful for determining the parameters needed for modeling the transport of chloride through the concrete cover layer. Furthermore, these techniques enable the different phenomena involved (matric suction, attenuation and hydrodynamic dispersion) to be treated separately, which is useful for modeling purposes.
