Influence of Quartz Fiber on Electromagnetic Wave Transmission Properties of High-Alumina Cement Paste
Bibliographic record
Abstract
In this paper, the effects of quartz fibers on the resistivity, complex permittivity, complex permeability, and S-parameters of high-alumina cement pastes are investigated. Meanwhile, the change of microstructure after adding quartz fibers were analyzed by mercury intrusion porosimetry (MIP) and scanning electron microscope (SEM). The results show that with the increase the content of quartz fiber, the real part of complex permittivity decreases, while the imaginary part of complex permittivity, dielectric loss tangent, and resistivity increased. At the same time, there are more small pores, and the interface situation is more complicated after adding quartz fiber. Therefore, the reflectivity decreases and the absorptivity increases, but the scope of increase in the absorptivity is smaller than the decrease in the reflectivity, resulting in an increase in the transmittivity. When the content of quartz fiber is 0.15, 0.30, 0.45, and 0.60%, the average transmittance of high-alumina cement paste is increased by 3.69, 6.18, 15.51, and 21.03% respectively. It is indicated that the quartz fibers can improve the wave transmission properties of the high-alumina cement paste.

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.
