Micro-scale and Meso-scale structure data for multi-level modelling of chemical species transport in concrete

Plurigaussian simulation, a discrete random field generation method, has been used to generate structural representatiosn of the micro- and meso- space of concrete, which are then coupled with a finite element model for simulating chloride diffusion. At both scales, the effective diffusion coefficients are calculated, and are used to calculate a range of effective diffusion coefficients at the macro-scale. In doing so, the variability at each scale is accounted for implicity at the macro-scale. Provided are the .vtk files which represent the micro- and meso-scale structure of the material, as well as a spreadsheet containing the calculated effective diffusion coefficients. The accuracy of the calculated effective diffusion coefficients was demonstrated through the consideration of a chloride diffusion test. The resulting chloride profiles are given in a spreadsheet.
