2.3. Experimental resultsFigure 2.7: SFRC samples to be tested in compression.2.3 Experimental resultsThe main mechanical proprieties determined in the experimental tests are presentedin the following subsections. At first, concrete specimens tested under compressionare proposed in subsection 2.3.1, then the experimental results on prismatic beamsloaded in four-point bending tests are detailed in subsection 2.3.2.2.3.1 CompressionThe results of compression tests are summarized in Table 2.4 in terms of cube compressivestrengths. The same table also reports the mean values of density measured inhardened samples of the various concrete mixtures under consideration.Table 2.4: Densities and cube compressive strengths measured in each mixture.Mixture LabelDensity [kg/m 3 ] R c at 28 days [MPa]white SFRC white SFRC (mean of two)REF 237142.59 (mean of three)S100-05 2376 2413 40.57 39.01S75-05 2411 2439 41.79 40.88LS50-05 2390 2430 44.80 43.36L75-05 2410 2428 48.03 45.41L100-05 2407 2443 43.70 42.74S100-10 2353 2488 40.33 44.91S75-10 2342 2458 38.44 39.54LS50-10 2362 2448 43.77 40.87L75-10 2391 2455 45.27 48.56L100-10 2418 2519 38.54 49.3935
