Appraisal of Hybrid Fiber Reinforced Engineered CementitiousComposite
Bibliographic record
Abstract
Mortar based engineered cementitious composite (ECC) demonstrate strain hardening behaviour with multiple micro-cracks under tension. The distinctive behaviour of ECC, makes it ductile as compared to brittle nature of conventional concrete. Ductile nature of ECC, makes it applicable in seismic resistant, repairing and retrofitting areas and blast resistant structural elements. In the present investigation, two types of polymer fibers (i.e. polyester (PET) fiber and polyvinyl alcohol (PVA) fiber) have been used in hybridization with different percentages (2+0), (2+0.5), (1.75+0.5), (1.5+0.5) for making ECC. Also fly ash, 55% of the total cementitious material, has been used for making sustainable concrete. The compressive, flexural and tensile tests were performed to evaluate the mechanical behaviour of hybrid fiber reinforced cementitious matrix. The test results revealed that PET fiber and PVA fiber in combination enhanced the strength properties of ECC by bridging effect of hybrid fibers.

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.
