The distributions of water content within mortar specimens were observed when water moved in one direction under three environmental conditions, namely drying, moisture absorption and water absorption. Numerical results were compared with the experimental data in order to examine whether the diffusion theory with non-linear equation is adequate for description of the behavior of the water movement. From the comparison, it is concluded that the diffusion theory is applicable to the above three conditions when diffusion coefficients and boundary conditions are suitably chosen. The mechanism of water movement within mortar is also discussed.
