Abstract
A modification of the testing procedure was adopted to improve the PERMIT ion migration test method, a non-destructive method to evaluate the quality of concrete in real structures. The steady state migration test procedure was reanalyzed from the viewpoint of electrolysis. The peak current obtained in the PERMIT ion migration test correlated well with the chloride diffusivity, the theoretical relationship between these was discussed and an equation for calculating the effective chloride diffusivity in concrete from the peak current was determined. The new process was found to be quicker and more effective than the typical process of the PERMIT ion migration test and to simplify the test procedure. As an application example, the effect of different controlled permeability formworks for improving the resistance of cover concrete to the penetration of chloride ions was investigated using the modified PERMIT ion migration test.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
