Abstract

Slurry infiltrated fibre concrete (SIFCON) is one of the recently developed construction material that can be considered as a special type of high performance fibre reinforced concrete (HPFRC) with higher fibre content. In the current research, triaxial compressive behaviours of high strength concrete (HSC), HPFRC and SIFCON were investigated. Purposefully, laboratory tests employed on four types of 75 × 150 mm cylindrical specimens with different steel fibres volumes (0, 2, 5 and 10%). All tests were conducted under four different confining pressure levels (0, 5, 15 and 21.5 MPa) according to triaxial conditions. Consequently, stress-strain curves were obtained and governing failure patterns and failure criterions of HSC, HPFRC and SIFCON samples were discussed. According to the results increasing of fibre volumes increases peak stress, energy absorption, toughness and Poisson's ratio while increasing confining pressures increases peak stress, energy absorption and toughness. Also, this may cause concrete to behave as a plastic material.
