| Outline of Final Research Achievements |
The objective of this study was to achieve quantitative evaluation of mass transfer in concrete and to clarify the mechanism of volume change which is caused by moisture transport. Firstly, micro pore model in concrete is developed by preparing micro channel on cement paste without pore on its surface. The mass transport in concrete was successfully evaluated with threshold pore, one of the indicators of pore structure. FIB-SEM was adopted to observe three dimensional pore structure in concrete with the dissolution of 10 nm. Supercritical Ar was applied to study the mechanism of volume change due to moisture loss.
