Abstract
Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) is a superior type of concrete with high strength in both compression and tension. The stress-strain relationship under uniaxial compression and tension is the premise for analyzing the mechanical behavior of UHPFRC components. This paper determines the stress-strain behavior of UHPFRC under uniaxial loading. The results of experimental investigations on the compression and tensile response of UHPFRC are presented. The experimental tests include 36 cylinders compressive tests and 36 dog-bone shaped tension tests to evaluate the stress-strain relationship of the material under compression and tension. The rigid auxiliary component and the deformation test frame were adopted in the compressive tests to obtain the decline curve successfully. Based on self-designed uniaxial tensile test equipment, a series of UHPFRC uniaxial tensile tests were completed. The effects of steel fibers content and water to binder ratio of the tensile and compressive strength, modulus of elasticity and post-cracking behavior was investigated.
