Abstract
Nowadays, low water-to-cement (w/c) ratio has been put into widespread use in engineering practice. However, low w/c ratio may give rise to high self-desiccation, which may lead to the decrease of early-age cracking resistance. Investigating the impact of w/c ratio on cracking resistance is utterly meaningful to better understand the cracking mechanism of concrete. However, the corresponding investigations remain lacking, especially when the ring test is utilized. In the present study, ring tests for three concrete mixtures with different w/c ratios were conducted to investigate the early-age cracking resistance of concrete from multiple parameters. Results showed that (i) the development rate of shrinkage of concrete for mixture W50 was slower than that for mixtures W33 and W40; (ii) the value and development rate of residual stress of concrete decreased when the w/c ratio increased; (iii) the relaxed stress for all mixtures developed rapidly at very early age, and reached the maximum value quickly; (iv) the cracking resistance of concrete increased when the w/c ratio increased at early age.

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
