Abstract:
To overcome the time- and resource-intensive electrochemical assessments used to evaluate the pitting corrosion resistance of stainless steel (SS) rebar alloys, a non-destructive assessment tool such as the Pitting Resistance Equivalent Number (PREN) index is important for decision-making involving building resilient engineering structures. By addressing the limitations of the existing PREN index, initially designed for SS alloys in hightemperature acidic or neutral environments, this study sought to develop a PREN index tailored for highly alkaline ambient-temperature concrete environments through a combination of electrochemical experimental analysis and machine learning modelling. This integrated approach and newly developed PREN index account for variations in SS alloying composition, concrete alkalinity, and environmental exposure conditions, addressing the growing demand for non-destructive, time- and cost-effective, and reliable alternatives for assessing SS rebar corrosion performance. Developed PREN will aid design of new and selection of existing SS alloys for reinforced concrete structures across diverse localities and applications. Two major formulas were reported, one for electrochemical parameters and the other for PREN related to these electrochemical parameters, each establishing their relationship with major SS alloying elements (i.e., Cr, Ni, Mo, Mn), concrete type (i.e. pH of testing solution), and concentration of deleterious species in exposure environment (i.e. chloride, sulphate). This study marks an initial step toward developing a non-destructive corrosion-performance assessment tool for civil engineering applications.

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.

Corrosion of reinforcement is a common deterioration problem for reinforced concrete structures at coastal areas causing early failure, increased maintenance costs, and significant safety problems. This paper combines a wellestablished diffusion-based service life estimation method with recently developed data-driven models on surface chloride concentration accumulation and critical chloride threshold distribution data to probabilistically analyze the effect of design parameters such as water-cement ratio (w/c), cover depth, and admixed chloride content in various coastal exposure zones. Results indicate that the used probabilistic analysis can result in changes to estimated service life values by an order of magnitude. Although w/c and cover depth were the most significant factors affecting the service life, parameters such as wind speed, temperature, exposure zone, and distance from the coast were identified as influencing the service life of coastal structures.

This article explores the evolution of Indonesia's concrete design codes, and how a foundation was built through decades of engagement with ACI standards. Through the Indonesian Society of Civil and Structural Engineers (HAKI) and ACI's shared commitment to excellence, a code born from colonial, Dutch origins evolved into a modern standard tailored to Indonesia's seismic realities.
