Arc Sprayed Zinc Metalizing for Cathodic Protection of Reinforced Concrete Structures
Bibliographic record
Abstract
Abstract Reinforced concrete structures can corrode if they are exposed to chlorides or if the pH of the concrete decreases over time. Arc-sprayed zinc coatings are versatile and can be used as part of a cathodic protection system to halt corrosion and extend service life. Arc-sprayed zinc coatings are multi-functional and can be used as part of impressed current cathodic protection systems or they can be used to provide galvanic cathodic protection. This paper describes the development and use of arc-sprayed zinc coatings for cathodic protection of steel in reinforced concrete structures. Arc-sprayed zinc coatings were first used in 1983 as part of an impressed current cathodic protection systems. Activated and inactivated arc-sprayed zinc coatings were first used for galvanic cathodic protection in 1988 System descriptions, project lists and performance data for arc-sprayed zinc in both impressed current cathodic protection and galvanic cathodic protection applications will be presented.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
