Assessment of Alkali–Silica Reaction Development in Portland-Limestone Mortar and Concrete with Different Limestone Replacement Ratios and Fineness
Bibliographic record
Abstract
In the present context of mitigating greenhouse gas emissions, interground portland-limestone cement (PLC) with elevated limestone filler (LF) replacement ratios (exceeding 15%) presents a feasible sustainable alternative, capable of diminishing clinker content. While LFs are known to modify the microstructure of concrete, the influence on ASR development has yet to be fully understood and requires further investigation. In this context, this work evaluates the effect of LFs replacement ratios between 15% and 25% on ASR development in concrete mixtures incorporating PLC. Analysis of expansion from accelerated mortar bar tests (AMBT) and concrete prism tests (CPT) indicate that increasing LF content from 15% to 25% does not substantially affect ASR-induced expansion. These findings underscore the viability of PLC as a sustainable construction material that does not compromise durability concerning ASR.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
