Experimental investigations to evaluate the alkali-carbonate reactivity and alkali-silica reactivity of aggregates
Bibliographic record
Abstract
The objective of this paper was to evaluate the alkali-silica reactivity (ASR) and alkali-carbonate reactivity (ACR) of the 14 aggregate groups quarried from different locations. In order to serve the stated purpose, the investigated aggregate groups were tested in determining their alkali-silica reactivity using the ASTM C 1260 at the ages of 2, 4, and 8 weeks, and the modified ASTM C 1293 (prisms submerged in the 1N NaOH at 80°C) at the test durations of 4, 8 and 13 weeks. The aggregate prone to the alkali-carbonate reactivity was accessed using the ASTM C 1105 at the ages of 3, 6 and 12 months. The study revealed that the aggregates susceptible to alkali-carbonate reactivity were also shown to be reactive due to the alkali-silica reactivity.

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.
