Data supporting "Traceable gradation design of a 100% recycled-fine-aggregate ultra-high-strength cementitious material: Directional strength and CT pore evidence"

This dataset contains the experimental data and derived numerical results supporting a study on a 100% recycled-fine-aggregate ultra-high-strength cementitious material. The deposited files include the complete L27 orthogonal screening and L9 refinement datasets, the L9_07 composition, the DF_01 Dinger–Funk q = 0.25 gradation record, the measured L9_07–DF_01 anchor comparison, directional compressive-strength replicates and statistics, Welch pairwise comparisons, the anisotropy index, a complete 84,091-row X-ray computed tomography pore table, pore-size summary results, authoritative RVE-scale porosity assessment results for 128–512 voxel windows, small-sample model benchmark results, and Hashin–Shtrikman/Mori–Tanaka analytical inputs and outputs. The dataset contains experimental data and derived numerical results only. Source code, analysis scripts and plotting scripts are not included. The full-resolution raw CT volume is not included because of its large file size and is available from the corresponding author upon reasonable request. All tabular files are provided in UTF-8 CSV format with accompanying documentation, a data dictionary, licence information and a file manifest.
