In this study, one-dimensional water absorption test was conducted along with DICM on small size oven dried concrete specimens of three different strengths. The changes of waterfront positions during the water absorption process and the progression of deformations in the saturated regions of mortar parts in concretes were clearly visualized in all specimens by utilizing DICM. The absorption characteristics determined from observations in DICM were related to the compressive properties and expansion strain in the same specimens.
