Evaluation of TiO₂-enhanced mortars for the protection of surfaces exposed to UV radiation
Bibliographic record
Abstract
This study evaluates titanium dioxide (TiO<sub>2</sub>)-enhanced mortars designed to protect surfaces exposed to ultraviolet (UV) radiation. The integration of TiO<sub>2</sub> into cementitious matrices aims to improve photocatalytic behavior and hydrophilicity, contributing to self-cleaning properties. A comparative analysis was conducted between modified and conventional mortars, all subjected to controlled UV exposure. Structural and compositional changes were investigated through X-ray diffraction (XRD) and X-ray fluorescence (XRF), while hydrophilicity was assessed via contact angle and droplet diameter measurements using distilled water. The results confirmed a progressive increase in rutile content and surface wettability in samples with higher TiO<sub>2</sub> dosage, demonstrating that UV-exposed TiO<sub>2</sub> mortars exhibit improved selfcleaning potential and structural stability. This approach offers promising applications in sustainable construction, especially in regions with high solar radiation.

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.
