Journal ArticleDOI
Influence of the interfacial zone on the chloride diffusivity of mortars
TL;DR: In this article, three different series of mortars with variable sand volume contents were cast in two different laboratories to study the influence of the interfacial transition zones (ITZ) on the transport coefficient of chloride ions.
Journal ArticleDOI
Chloride binding capacity of various hydrated cement paste systems
TL;DR: In this paper, the interaction mechanisms of the cement paste hydration products with chloride were investigated for various systems, including water/binder ratio (0.25 and 0.45), type of cement (ASTM type I, III, and V), use of silica fume (6%), and chemical composition of the chloride solution.
Journal ArticleDOI
Modelling of the transition zone porosity
TL;DR: In this paper, the porosity of the transition zone has been analyzed as a function of the mortar composition and of the degree of hydration, and the analysis of percolation through a 3D mortar model has been carried out.
Journal ArticleDOI
Numerical simulation of multi-species transport through saturated concrete during a migration test - MsDiff code
TL;DR: In this paper, a numerical model called MsDiff (Multi-Species DIFFusion) based on a finite difference method and on the Nernst-Planck relation has been developed.
Journal ArticleDOI
Numerical simulation of multi-species diffusion
TL;DR: In this article, a numerical model was developed to simulate the transport of several ionic species across a saturated concrete or mortar sample by using the Nernst-Planck system of equations.
