Synergistic Impact of Sustainable Graphene Derivative and Dune Sandon Cement Mortars
Bibliographic record
Abstract
This study investigates the impact of a sustainable graphene derivative, designated as D-GSH, on the compressive strength development of cement mortars.The research evaluates the effects of D-GSH addition by 0.25%, by weight of cement, and dune sandto-cement ratios on compressive strength at 1, 7, and 28 days.Compressive strength tests reveal that the addition of 0.25% D-GSH significantly enhances strength across all age intervals, with increases of 13%, 55%, and nearly 50% at days 1, 7, and 28, respectively.Conversely, increasing the dune sand-to-cement ratio from 1:1 to 1:3 adversely affects early strength development.While the higher sand content initially boosts strength, its long-term performance is hindered, highlighting the necessity for optimal dune sand content in cement mortars.The findings demonstrate that D-GSH effectively accelerates early strength gain, making it a viable alternative for improving the performance of cement-based composites.

How this classification was reachedexpand
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.
