Multi-phase modelling of ionic transport in concrete when subjected to an externally applied electric field
This is the first demonstration of solving Poisson’s equation to get numerical solutions of ionic transport in concrete with electric field; traditionally the Laplace equation is used, which is only an approximation of Poisson equation. The model not only highlights the influence of the assumption of electro-neutrality on ionic transport in two-dimensional, two phase problems but also provide a way in which the influence of tortuosity on both the diffusion and migration of ions can be accurately assessed. The work has led the development of an international network for which an EU grant is recently awarded to Plymouth.
