Abstract

fetched live from OpenAlex

The purpose of this study is to explore the mechanical properties of concrete at different curing ages after freeze-thaw cycles in most areas of the plateau where freeze-thaw cycles exist. By comparing the compressive strength and splitting strength of concrete at different curing ages after different freeze-thaw cycles, the influence of curing age changes on the mechanical properties of concrete after freeze-thaw damage was analysed. The results show that the compressive strength and splitting strength of concrete can be significantly increased by increasing the curing days of concrete with the same number of freeze-thaw cycles, and sufficient curing age has a significant effect on reducing the influence of freeze-thaw cycles. Under the condition of the same curing days, with the increase of the number of freeze-thaw cycles, the compressive strength of concrete will first increase and strengthen at 50 cycles, and then start to weaken continuously. The splitting strength will continue to decrease with the increase of freeze-thaw cycles.

Teacher imitation

Not 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.
