Abstract

fetched live from OpenAlex

This paper presents the results of a research work to develop ferrocement sandwich and hollow core panels for use as precast one way slab elements. Sandwich panels consisted of two thin ferrocement layers reinforced with steel wire mesh and a core of autoclaved aerated lightweight concrete bricks. The hollow core panels are made of the same ferrocement mortar matrix with three circular holes of 75 mm diameter running along the length of the specimen. A total of 15 sandwich panels and 12 hollow core panels were cast and tested under flexural loadings. The experimental results showed that high ultimate and service loads, crack resistance control, high ductility, and good energy absorption could be achieved by using the proposed panels. A theoretical model based on the ultimate strength method for reinforced concrete was developed to determine the ultimate moment and mode of failure of the panels. The theoretical and experimental results showed good agreement.

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.
