Abstract: The durability of a concrete structure is related to its ability to impede, or greatly reduce, the rate of fluid transport. Substantial research has been performed to assess the durability of concrete structures. The majority of previous research has focused on the fluid transport and durability performance of undamaged concrete. Comparatively, little work has quantitatively described how performance changes when cracks are present. The incorporation of cracking in numerical models can be complicated. This paper begins the process of developing a modeling approach that considers cracks through a ‘crack-like’ geometry that is prepared using a saw-cut notch. This paper describes the use of x-ray absorption to determine the spatial and timedependant fluid movement. The results of the x ray measurements are correlated with fluid transport models.
