Abstract:
This research was conducted to develop new test methods for measuring compressive strength, tensile strength, flexural strength, and chloride ion diffusion coefficient of minute regions in concrete. These test methods are specially designed to characterize the properties of the minute regions taken from concrete specimens. It is expected that this study provides a set of tools to understand the heterogeneous structure of concrete. In summary, it can be concluded that the strengths and the chloride ion diffusion coefficient of minute regions in concrete, which have not hitherto been quantitatively evaluated, are established.
