- Synopsis
- The establishment of technology to assess the mass transfer characteristics of cover concrete by nondestructive and semi-destructive means is needed. This paper introduces an original non-destructive method called the seal method for assessing air permeability, which is one of the indexes of mass transfer characteristics, and a framework for converting the obtained air permeability index and moisture content of the concrete into the effective diffusion coefficient of chloride ions, which cause deterioration of RC structures.
- Keywords:
- air permeability, air permeability test, moisture content, effective diffusion coefficient of chloride ion, non-destructive test, seal method
