Moisture transport in cracked concrete is one of the most important key phenomena which determines the deterioration of concrete structures by introducing undesired elements. Especially, the anomalous moisture transport of cement-based material, which does not follow the root-t law, should be explicitly understood. Since the calcium silicate hydrate, which is a major phase of cement-based materials and shows volume change as a function of water content, is the main reason for the anomalous moisture transport by changing the microstructure and macroscopic volume change of cement paste in concrete, these behaviors are explicitly and numerically taken into account in the moisture transport by using truss network model (TNM). This moisture transport model is coupled with a rigid-body spring network model (RBSM) which deals with cracks easily. The moisture transport in the cracked concrete was simulated and compared with the experiment and discuss the mechanisms of anomalous moisture transport.
