Influence of water-to-binder ratios on the performance of limestone calcined clay cement-based paste for mining applications
Bibliographic record
Abstract
This study aims to investigate the impact of various water-to-binder (w/b) ratios by mass (0.3–2.0) on the performance of limestone calcined clay cement (LC 3 ) pastes. The flowability, setting time, density, unconfined compressive strength, hydration, and microstructure of LC 3 pastes under different w/b ratios were thoroughly investigated. The results show that increasing the w/b ratio extends the flowability and setting time while significantly reducing the unconfined compressive strength of LC 3 pastes. LC 3 pastes with w/b ratios above 0.6 exhibited a final flow diameter surpassing 167 mm, indicating good flowability. The 28-d unconfined compressive strength decreased from 82.3 to 1.3 MPa as the w/b ratio increased from 0.3 to 2.0. This study confirmed that the relationship between unconfined compressive strength and the w/b ratio of LC 3 follows Abram’s law. Furthermore, a modified gel/space ratio was proposed to reflect the concentration of solid products, effectively explaining the influence of the w/b ratio on strength, with an R 2 of 0.96.

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.
