Abstract
It has been well established that supplementary cementitious materials (SCMs) can significantly enhance the resistance of concrete to chemical sulfate attack. However, the effect of SCMs on the durability of concrete exposed to physical salt attack is still controversial. To date, there have been only limited studies that have investigated this concrete durability issue. Therefore, the present study investigates the effects of using different types of SCMs, including silica fume, fly ash and metakaolin, in concrete subjected to environments prone to physical salt attack. Results indicate that the damage of concrete escalates as the addition level of SCMs increases. An attempt is made to delineate this problem and explain the mechanisms controlling this behaviour, which could have implications for existing design codes. The findings call for caution when SCMs are specified for concrete subjected to environments conducive to physical sulfate attack.

Full frame distilled prediction
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
