Sustainability of civil infrastructure construction can in part be attained by better testing to identify important material characteristics that affect durability. The quality of the concrete in reinforced concrete structures is a primary factor that enhances corrosion durability of reinforced concrete structures. The concrete may be assessed for quality control using methods such as bulk ion diffusivity tests, accelerated electrical migration tests, and electrical resistivity. There is interest in non-destructive in-situ testing for assessment of structures in service. In this study, preliminary tests were conducted to characterize the durability of concrete using a water permeation test, acoustic testing, as well as electrochemical impedance spectroscopy. Test results showed that the electrical properties of the hardened concrete can be assessed by electrochemical impedance spectroscopy where a high frequency impedance loop (relating to the bulk material and internal moisture content) can be discerned. The concretes with lower water-to-cement ratio and larger coarse aggregates showed larger resonant frequency values that can be attributed to greater developed stiffness. A water permeation test was also demonstrated to differentiate internal moisture conditions, and its results (described by a decay factor derived from mass and energy balance) was well correlated to its concrete electrical parameters.
