| 要旨 |
Drying experiments of both cement mortar and concrete specimens have been done to evaluate water movement behavior in cement based material. Boltzmann-Matano method is applied to the experimental data to calculate the water diffusion coefficient. Temperature dependency of water diffusion coefficient and effect of aggregate size on water diffusion coefficient are experimentally evaluated. As a result, temperature dependency of water diffusion coefficient is governed by power law and the aggregate size doesn’t have much impact on water diffusion coefficient. |
