Abstract
One of the major durability issues in concrete structures is the cracking resulting from shrinkage. Drying shrinkage contributes a major portion of shrinkage strain in conventional concrete. Controlling the drying shrinkage of concrete can lower the total shrinkage strain and subsequently reduce the extent of cracking and enhance the durability of concrete structures. The objective of this study was to develop a pulp fiber-based concrete to reduce the drying shrinkage and microcracks in concrete. Using superabsorbent cellulose fibers (SCFs) in the concrete mix, this study intended to develop a concrete mix with acceptable properties with reduced shrinkage strain and cracking. Using scanning electron microscope images, crack growth in different concrete specimens with and without SCFs was observed. Free shrinkage tests were conducted to investigate the efficiency of SCFs in controlling concrete shrinkage. The test results indicated significantly reduced crack widths and a lower shrinkage strain in concrete containing SCFs.

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
