Database of chloride concentration profiles on naturally degraded structures in marine and deicing salt environments

This database contains 150 chloride concentration profiles selected from the scientific literature to support the global evaluation of service life prediction models for reinforced concrete structures. The dataset includes chloride profiles obtained from naturally degraded structures exposed to marine or deicing salt environments, located across all five continents and covering a wide range of climatic conditions. Each profile provides chloride concentration values as a function of depth in concrete, together with information about the exposure environment, location, and characteristics of the source structure. The data were collected and organized following a standardized protocol to ensure consistency and comparability between different studies. The purpose of this database is to provide a reliable basis for modeling chloride transport under diverse exposure conditions and for verifying the generalization of predictive models of chloride concentration over time. The individual data sheets for all 150 chloride profiles are presented in the document.
