Abstract
In this paper the properties of self-consolidating concrete (SCC) used for repair applications and prepared with two commercially available ternary blended cements and chemical admixtures such as a high-range water reducer (HRWR) and a viscosity modifying admixture (VMA) were investigated under restrained shrinkage. The examined properties include compressive strength, indirect tensile strength, static elastic modulus, free shrinkage, and restrained shrinkage. From the results, it became clear that the resistance of SCC to shrinkage crack was quite different depending on the nature of HRWR and the binder type in use. The cracking age increases in mixtures proportioned with polycarboxylate (PC)-based HRWR compared with polynaphthalene (PNS)-based HRWR. The SCC mixtures based on blended ternary cement containing Class F fly ash show shorter cracking age than the corresponding SCCs proportioned with ternary blended cement containing slag. Finally, it was found that the potential of shrinkage cracking of SCC is not influenced only by the amount of shrinkage but also by the shrinkage rate and tensile creep.

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
