Abstract:
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.

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.

This article discusses key sustainability components for existing concrete structures, including safety and structural performance, environmental management, and durability design and service-life extension. It also presents the results of a survey about current university/college level courses and focus programs associated with these topics being offered by various institutions.
