Abstract

fetched live from OpenAlex

Chloride profiles are used to select concrete compositions for new reinforced concrete structures, evaluate the condition of existing structures, and to predict their remaining service life, all with regard to chloride-induced reinforcement corrosion. They are invaluable tools for improving the sustainability of our infrastructure. We examine what chloride profiles tell us and how they should be used. Through a series of case studies, we establish a list of crucial research questions that provide a direction for future research in this field: What is the contribution of chloride binding to chloride transport? What is the path for chloride transport in concrete? How are our findings on chloride profiles relevant for reinforcement corrosion? We then discuss the implications of the answers to these questions for engineering and mechanistic modelling practices.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
