Abstract: The primary objective of this paper is to investigate the reliability of the new fib Model Code 2010 (MC 2010) to classify and characterize a fiber reinforced concrete (FRC) mix design developed for the hydropower company Furnas Centrais Elétricas in Brazil. One of the most important aspects of FRC regards its heterogeneity, which is directly related to the amount, alignment and distribution of fibers in the bulk concrete. The lack of design codes imposes a barrier to the development of the full potential of this material for structural applications, which remains mostly used for concrete crack control and durability purposes. The introduction of design rules for FRC characterization and classification in the new fib Model Code represents a significant step forward in the rationalization of its applications. In this project, three-point bending tests were carried out to obtain the material class. From the latter, FRC constitutive law in tension was determined. To verify MC 2010 reliability, indirect tensile Double Edge Wedge Splitting (DEWS) tests were performed and compared with the FRC constitutive law. The comparison of the results demonstrated that the design procedures described in MC 2010 are reasonable and are on the safe side.
