　　X-ray tomography (X-CT) was applied to track in-situ, continuously and visually the migration process of water in unsaturated cement pastes.The effects of water to cement ratio were investigated.According to grey values and pores spatial distribution in X-CT images, it indicates that the profiles of water suction starts with an early rapid growth and a subsequent slowly increasing period which followed by a relatively stable stage.The rate of water penetration is accelerated with the increasing water-to-cement ratio.
