Dual-age strength and mixture evaluation dataset for gypsum-containing cementitious and backfill materials
Description
Numerical data underlying the manuscript "Dual-age Strength Development and Mixture Evaluation of Gypsum-containing Cementitious and Backfill Materials". The deposit contains the 41 mixtures from two published sources — 16 flue-gas desulfurization gypsum–cement–fly ash–slag cementitious mixtures (Source A) and 25 fly ash–carbide slag–slag–gypsum clinker-free backfill mixtures (Source B) — with their mixture compositions, 7-day and 28-day compressive strengths (MPa) and derived strength gains, plus all cross-age rankings, factor-level statistics, model errors, ranking-retention and selection-loss metrics reported in Tables S1–S22 of the supplementary material. The underlying experimental data originate from the two published studies cited as references [1] and [2] of the article; all derived quantities were generated in this study. Model training scripts are not included; all numerical results are also supplied with the article as supplementary material.

Steps to reproduce
1.Open Dual_age_strength_and_results.xlsx in Excel, LibreOffice or pandas. 2. Worksheets S01–S22 reproduce every supplementary table exactly as printed, including bracketed ranges and categorical annotations. 3. Worksheets Source_A_16_mixtures and Source_B_25_mixtures contain numeric compositions and strengths for direct reuse: 7–28 d gain = 28 d strength minus 7 d strength; rankings and factor-level statistics follow the definitions in Table S1. 4. All model-related results (MAE, RMSE, bias, ranking retention, selection loss, attributions) are tabulated in S08–S21 so each reported value can be checked against the workbook. See README.md for provenance and scope.
