Title: Capillary Flow Analysis of Water Movement Within Mortar

Abstract:The non-linear diffusion equation has been successfully applied to water movement but only during the drying process. As a model which can be applied to both drying and wetting processes, capillary flow is considered to be worth examining as one possibility in order to establish a universal model. In the first step, one-dimensional water movement within mortar was studied both analytically and experimentally. A model consisting of capillaries with various sizes was adopted and water movement was analyzed by assuming that it was caused by capillary action. A good correlation w a s obtained between numerical results and experimental data. Useful information was also obtained from the analysis concerning the behavior of moving water within mortar.
