Abstract
This paper presents series of experimental studies on newly developed basalt fiber reinforced polymer (FRP) grids for the flexural strengthening of reinforced concrete beams. The study includes tensile behavior of the basalt FRP grids with three types of thickness, bonding behavior between the basalt FRP grids and the concrete with epoxy resin, and flexural behavior of the reinforced concrete beams strengthened with basalt FRP grids. The results revealed that the modulus of elasticity of the basalt FRP grids ranged between 40 and 43 GPa, and their tensile strength ranged between 815 and 931 MPa. The bond stress–slip behavior of the basalt FRP grids and concrete exhibited a ductile failure manner in comparison to that of FRP sheets and concrete; the bond strength of the tested basalt FRP grids was in the range of 3.26–6.06 MPa, and its slip at peak ranged between 0.15 and 0.4 mm. Beams strengthened with basalt FRP grids failed by crushing of compressive concrete or fiber reinforced polymer rupture and no debonding failure was observed for any of the tested beams.

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
