| Abstract | Permeability is one of the most important geophysical parameters, which unfortunately is quite difficult and time consuming to be tested and estimated for concrete. Additionally, Prediction of permeability based on geophysical measurements is currently one of the most challenging issues in geophysics. There have been recently reported some important relationships between permeability, resistivity and induced polarization (IP) parameters for a different samples including cement admixed clay samples, sandstones and concrete. However, the disadvantage of this approach is the very scarcity of IP data as most of practical measurements are time-domain IP. In this research, an innovative approach using resistivity and chargeability measurements to predict permeability of concrete was proposed and successfully applied for tested samples based on measurements of resistivity and time domain IP data for two different types of electrode configurations. Total number of 12 samples were made including 6 specimens from each electrode configuration with 2 different sizes of concrete specimens were tested for 56 days of curing process. The permeability predicted by resistivity and chargeability model in this research matched well with permeability measured by consolidation testing. |
