Behavior of UHPFRC at High Temperatures
This chapter presents the results of an experimental study carried out at high temperatures on two industrial ultra high performance fiber‐reinforced concrete (UHPFRC) containing polypropylene fibers: Ductal®‐‐AF and BSI®‐“fire”. Hot and residual compression tests with and without preload were carried out from 90°C to 700°C. The chapter presents the evolution of the stress/strain curves, the compressive strength and modulus of elasticity with temperature. Moreover, an unusual thermal dilatation of concrete, i.e. non monotonic was observed. Then, the chapter discusses several fire resistance tests on large‐scale elements and smaller samples. The fire scenarios applied were ISO 834 and modified hydrocarbon curves. In most cases no spalling was observed. Comparison with results obtained on reference UHPFRC without polypropylene fibers shows the effectiveness of these fibers for these materials and these geometries in reducing the spalling risk.
