Abstract

fetched live from OpenAlex

For aggregate-free, calcite-containing lime binders, we correlate long-range crystallinity parameters from X-ray diffraction measurements (lattice constants, crystalline domain sizes, and microstrain fluctuation values) with short-range structural parameters from extended X-ray absorption fine structure data (coordination environments, attenuation factors, and fit stabilities). In doing so, we reveal a correlation between unit cell contraction and a more ideal local calcite structure. Using Fourier transform infrared spectroscopy and X-ray absorption near edge spectroscopy, we rule out the possibility of contributions from amorphous calcium carbonate and show that the structural disorder is likely related to localized regions of incomplete carbonation. Thus, by using data from this judicious combination of structural characterization tools, we demonstrate that short-range structural distortions occur in calcitic lime binders and that these distortions can be detected even in multiphase mixtures.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
