Abstract
Concrete is a construction material which service life can be significantly reduced with the

presence of cracks when concrete is exposed to aggressive agents such as chlorides. The

current service life models for concrete do not account for cracks when modelling service

life of concrete structures. In this thesis, moisture transport in concrete with a crack and

aggregates was modelled numerically using finite element analysis. The numerical model was

applied to a wedge spitting test geometry and tested against experimental data, and was used

to identify how the crack and aggregates influence moisture ingress. The numerical model was

able to model the ingress extend in vertical and lateral directions with a very good

agreement with the experimental data, both for the un-cracked and cracked state. The moisture

distribution was more accurately modelled with the heterogeneous models including aggregates

compared to the homogenous models without aggregates. By observing the behavior of the

numerical model when varying the number of solutions that is interpolated and averaged to

give rise to the heterogeneous models including aggregates, it was found that the

heterogeneous models converge towards the homogenous models, when the number of interpolated

solutions that are included go towards infinity.
