Modelling moisture transport in intact and fractured concrete

P. Moonen and J. Carmeliet,     ETH Zürich and Empa Dübendorf, Switzerland

Abstract:

Material degradation results from the complex interaction between physical, chemical and biological degradation processes. Moisture transport plays a crucial role in many of these processes and is therefore of particular interest. This chapter starts by reviewing the state-of-the-art in the modelling of moisture transport, both in intact and in fractured materials. It is shown that the quality of the model predictions crucially depends on two material properties, namely the capacity and the permeability, and that the experimental determination of these properties remains challenging. Next, the ...
