Abstract:	The aim of the paper is the characterization of the mechanic properties and the constitutive law, for the usual utilization in the design practice, of the composite Fiber reinforced concrete material (FRC). Nowadays in this field a great interest is represented for this material, both new structural element construction and external application of a thin layer in old or damaged conventional concrete elements. The addition of polymeric or steel fibers to a cementitious matrix increases the tensile strength and provides a residual strength in tension: this condition particularly proves, for usual content of fiber (1% - 2%), that the FRC material presents softening branches and residual strength; on the contrary for larger content of fiber (almost 4%) the global response of the FRC material is ductile and the dangerous phenomena of strain localization generated near the cracks is more reduced. This condition produces the possibility of optimal use of the new material in the str...
