Data and Code for “Using international public data at data-scarce ready-mixed concrete plants: selecting a source-defined predictor with one 28-day result”

This dataset contains the reproducibility materials associated with the manuscript “Using international public data at data-scarce ready-mixed concrete plants: selecting a source-defined predictor with one 28-day result.” The study evaluates whether international public concrete data can support predictor selection for data-scarce ready-mixed concrete plants. Ten Public source blocks were used to construct 1,023 fixed source-defined predictors, and External source units were used to develop and evaluate a one-result predictor-selection workflow. A planned mixture set is used to nominate an X-centroid Sentinel before strength is known; after one 28-day Sentinel result becomes available, the workflow selects an existing predictor without local refitting or calibration. The repository contains the Public and External source registry, processed data that are permitted for redistribution, source data underlying figures and tables, analysis code, and fixed model artifacts required to reproduce the reported analyses. Original third-party datasets that cannot be redistributed should be obtained from their cited sources as identified in the source registry. Historical Local production records are not publicly included because they contain plant-level operational information and are subject to authorization by the data owner. The archived materials correspond to the version of the analysis reported in the associated manuscript.
