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.

ACI Committee 365 published a new Design Specification in 2024. The Design Specification was developed to provide requirements to the Service Life Engineer, a specialty engineer focused on durability, for performing service life predictions of new structures. The Service Life Engineer is responsible for predicting the service life performance of concrete elements and developing requirements for the verification of the service life prediction during construction. The Service Life Report, developed during or prior to construction, and a Service Life Record Report, delivered at the completion of construction, are deliverables prepared by the Service Life Engineer at the completion of the project. The requirements of the Design Specification aim to provide consistency to the practice of service life prediction of new concrete structures. The technical requirements for performing service life predictions following the Design Specification are discussed in this paper.

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.
