Abstract
Concrete is a brittle material. Numerous studies were performed on increasing the ductility of concrete. Steel fibres were widely used in concrete because of its advantages on the toughness, ductility and strength properties of steel fibre reinforced concretes (SFRCs). Owing to improving the bond properties between fibre and matrix, hooked-ended steel fibres are mostly preferred in SFRCs. In this study, the effect of type of hooked-end fibres on a high performance concrete (HPC) were investigated by an experimental research. Three different hooked-ended steel fibres were added in four different volume fraction in a high performance concrete. Fracture energies and mechanical strengths of concretes were determined by flexural tensile strength tests. Test results showed that there were significance effects of types of hooked-end on post cracking behaviour and fracture energy of high performance steel fibre reinforced concretes (HPSFRCs).
