Abstract

fetched live from OpenAlex

In this study, the relationships between the percentage of reactive andesitic aggregates contained in river gravel, the alkali and chloride content in concrete and the degree of deterioration of concrete due to ASR in Hokuriku region were investigated by means of the visual inspection for concrete structures and the various tests using the cores taken from them. The applicability of accelerated curing method according to the Canadian and Danish specification to evaluate the alkali-silica reactivity of aggregate or the residual expansion ability of concrete was comparatively examined. By judging from the results of inspection whether or not the expansion of ASR-affected concrete structure had already been stopped, the appropriate repair and maintenance method should be adopted for the individual one.

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. 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.
