Abstract:
Resistivity can be implemented in quality assurance and quality control operations to assess concrete durability. This article describes a U.S. Department of Transportation Small Business Innovation Research (SBIR) program project Callentis Consulting Group and Penn State University collaborated on to develop a practical device for measuring pore solution resistivity (PSR) and mixture resistivity and to provide direct calculation of formation factor (FF).

In September 2025, ACI brought together international voices from ACI chapters during its International Chapter Roundtable held in conjunction with the 3rd International Workshop on Durability and Sustainability of Concrete Structures in Naples, Italy. Participants represented the United States, Canada, Italy, Morocco, the United Arab Emirates, Egypt, Iraq, the United Kingdom (Institute of Concrete Technology), and Greece. The 2025 edition of Jeddah Construct featured a panel discussion titled “Defining Green: Perspectives on Sustainability in Concrete Construction.” The session was moderated by Ahmad Mhanna, ACI Director for the Middle East and North Africa Region.

It is well known that the steel–concrete interface (SCI) influences corrosion of steel in concrete. Numerous factors related to the SCI have been hypothesized to affect the mechanism of corrosion initiation and propagation, including steel surface characteristics, interfacial concrete properties (voids, cracks, etc.), and conditions related to the exposure (e.g., SCI moisture state). This contribution offers an overview of current knowledge on these aspects. Additionally, recent advances toward a fundamental understanding of corrosion-related processes occurring at the SCI are highlighted, including a novel experimental methodology for studying the steel surface behavior, imaging of the SCI moisture state, and the impact of macroscopic voids. Finally, perspectives for future research are given.

Reinforced concrete is prevalent in construction for its strength and longevity. However, it can be susceptible to corrosion when exposed to chloride ions, particularly in areas affected by de-icing salts and marine environments. The technique known as Electrochemical Chloride Extraction (ECE) helps combat this corrosion by pulling chlorides away from the reinforcing steel and raising the concrete's pH around the steel. This paper examines the technique's development, the electrochemical reactions, and its effects on corrosion rates. Although ECE can dramatically lower chloride-induced corrosion, immediate post-treatment measurements often reveal increased corrosion rates as the passive oxide layer is re-established. A comparison of Linear Polarization Resistance (LPR) measurements before and after ECE illustrates the technique's effectiveness.

Concrete is an efficient material in terms of mechanical strength and functionality, but whose durability is one of present challenges that need particular attention to preserve the reinforcement absent of corrosion during the nominal service life. Present trends on modelling by performance make more complex the quality control testing and lengthens the characterization of new low carbon cement concretes. In present work is presented concrete resistivity as the single parameter able to characterize both corrosion periods through the corresponding mathematical expressions. Resistivity is a non-destructive test which could qualify concrete from its early ages. Based in the relation between diffusivity-corrosion current and resistivity, an integral model based in the resistivity measured at short term in the same specimens than mechanical strength (cured humid), is described. It is also analysed the analogies between the diffusivity and corrosion current and the influence of climate in the resistivity for future challenge of predicting the impact of climatic change.
