Abstract: Ultra-high performance fiber reinforced concrete (UHPFRC) is considered a promising material for many applications where high compressive and tensile strength, small thickness and high energy absorption capacity are required. However, although these materials were introduced in the mid-1990s, a comprehensive investigation regarding its tensile characterization is still particularly challenging. Different tensile test setups have been used by many researchers, in order to obtain reliable results, but today there are currently no testing standards available that define test conditions, specimen geometry and analytical procedures to fully characterize the tensile properties of UHPFRC. In this study, the tensile behaviour of UHPFRC has been investigated with direct tensile tests on dog-bone specimens, using a gripping system with rotating boundary conditions. Tests have been performed in displacement control. Digital Image Correlation (DIC) has been used to measure displacements, deformations, number and width of cracks in experimental testing. The effect of hooked steel fibers with diameter of 0.38 mm and length of 30 mm on the tensile behaviour of UHPFRC has been investigated, varying the amount of fibers from 0% up to 2.6% by volume. The fiber volume fraction greatly influences the tensile strength of the material, strain at peak strength, energy absorption capacity and post-cracking behaviour.

Abstract: Ultra High Performance Fiber Reinforced Concrete (UHPFRC) is an innovative material with great mechanical and durability performances, high ductility and toughness. Although the mechanical behaviour of UHPFRC has been extensively studied in the last years, the damage mechanisms and permanent strains of this material when subjected to flexural loads need to be further investigated, in order to quantify and to better predict the performance of UHPFRC structural elements.
