Sulfate-Induced Degradation in Concrete Exposed To Thermal Gradient
Bibliographic record
Abstract
This study investigates the effects of external sulfate attack on concrete subjected to a thermal gradient.For this purpose, mortar beams measuring 40 40 160 mm were immersed in a 10% w/v MgSO solution for up to 120 days.Three distinct temperature and humidity conditions, M2P, M5P and M5F, were simulated.The beams subjected to M2P and M5P conditions were partially submerged in the sulfate solution at 22C and 50C, respectively, whereas the M5F samples were fully immersed.Preliminary findings indicate that samples exposed to M5P experience the most severe physical degradation.Additionally, M5F samples exhibit the highest mass and volume gain, whereas M5P samples show the greatest loss in mass and volume after one month of exposure.In future studies, the mechanical and microstructural changes due to sulfate attack for the three exposure conditions will be investigated.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
