3DP_CONCRETE_BEAMS_SERIES_2

Dataset "3DP_CONCRETE_BEAMS_SERIES_2" presents the results of experimental research conducted on concrete beams subjected to three-point bending, manufactured using an additive 3D printing method. The specimens were printed with two different single-layer dimensions of 10 × 20 mm and 15 × 30 mm,  using one-component mixture Sikacrete 751 3D . The beams had dimensions Leff × D × t: 180 × 60 × 60 mm (Leff — distance between supports, D — effective depth, t — thickness) and v.u. layer orintation.  During testing, the beams were gradually loaded at the top edge under displacement control, while the deflection was measured at the bottom edge at mid-span.
The results for each beam are stored in three columns: (1) time [s], (2) load [N], and (3) deflection [mm]. The first row contains the specimen number, while the second and third rows describe the measured parameters and their units. The datafile is split into four worksheets  "S2_10x20" (dry specimens) and "S2_10x20_W" (wet specimens) inclue results  for beams consituted of a single-layer of 10x20 mm, while  "S2_15x30" (dry specimens)  and "S2_15x30_W" (wet specimens) inclue results  for beams consituted of a single-layer of 10x20 mm. 
Datasets "3DP_CONCRETE_BEAMS_SERIES_1", "3DP_CONCRETE_BEAMS_SERIES_2", and "3DP_CONCRETE_BEAMS_SERIES_3" were developed within the same research project (MINIATURA-7, 2023/07/X/ST8/01392) and include results for beams with different geometries.
