Two bricks with different transport parameters were used in combination with two different mortars: a lime hydrate mortar and a cement mortar. Water transport was monitored during the first two hours after contact using X-ray imaging and modelled using the finite element code Hamfem. The amount of desorbed water after two hours depends more on the mortar than on the brick. The rate of flow across the interface shows a complex behaviour in the experiments, which is not entirely captured by the model: there is an overshoot in flow, followed by a reversal of flow direction. The accuracy of simulations is also limited by the importance of over-capillary effects in the bricks near the interface. It appears that this over-capillary water is only partly distributed over the brick, and partly reabsorbed by the mortar.
