This XLSX workbook contains laboratory experimental data for nine UHPC mixtures (CZ1–CZ9) and six UHPFRC mixtures (CS1–CS3 with 0.5%, 1%, and 2% steel fibers, and CP1–CP3 with 0.5%, 1%, and 2% PVA fibers). The workbook includes compressive strength results at 3, 7, 14, 28, and 90 days, with approximately six repetitions for each test condition. It also includes the 28-day characteristic compressive strength (f_ck), splitting tensile strength at 28 days, and slump test results for all mixtures. In addition, the workbook provides statistical summaries, including mean value, maximum, minimum, standard deviation, and coefficient of variation, as well as graphical probability distribution functions for compressive strength across the different mixtures. These data support the experimental characterization and comparative analysis of the mechanical behavior of UHPC and UHPFRC in the PhD research project.
