Abstract: The performances of fiber-reinforced self-compacting (FR-SCC) concrete under compression are investigated. In general, its ductility is comparable with that of normal vibrated concrete (NC) and self-compacting concrete (SCC) in the presence of confinement. This aspect can be evidenced by analyzing the mechanical behavior of cylindrical specimens under uniaxial and triaxial compression. The post-peak response is defined in terms of F(w), which is the nondimensional function that relates the inelastic displacement w and the relative stress during softening. In the case of SCC, the presence of fibers increases the value of F(w) in correspondence of given values of w. Starting from this performances, the mechanical behavior of a low-carbon footprint SCCs is also considered. The results of this study seem to confirm that the idea of introducing a new generation of concrete mixtures, capable of maintaining high values of F(w) with a reduced amount of cement, is not a chimera.
