Abstract: In response to demands for higher strength, higher performance and multi-functional construction materials for use in specialized structures, advanced concretes have been introduced. One of their features is high tensile strength. Among the advanced concretes, Ultra High Performance-Fiber Reinforced Concrete (UHP-FRC), introduced in the mid-1990s, is the most advanced. UHP-FRC can be generally defined by their superior compressive strength (over 150 MPa) and by the presence of fiber reinforcements to decrease brittleness and enhance tensile capacity. To characterize tensile behavior of UHP-FRC under wide range of strain rates, a hydraulic servo-controlled testing machine and a newly proposed impact testing system were used. Four strain rates ranging from quasi-static (ε̇ = 0.0001 1/s) to seismic (ε̇ = 0.1 1/s), and strain rates ranging from 90 to 146 1/s, respectively, were achieved using two testing systems. All UHP-FRC cases tested in this experimental program show remarkable strain sensitivity. A preliminary research on durability test is also carried out to evaluate long term behavior of high performance fiber reinforced concrete.
