Özet

With the developments in the construction sector, the use of fiber in concrete technology has gained great importance due to the developments of the spread of high rise concrete buildings, the increasing importance given to infrastructure, investments in nuclear energy field. Therefore, it is clear that this fiber reinforced composite especially should have also ductility properties. Fiber reinforced composites are designed in order to prevent extremely structural collapse by absorbing massive amount of energy during extreme load-displacement events such as earthquakes, projectile impacts and explosions. It will be much more possible with using this composite in the construction sector to construct much higher concrete building, increase the economic life and strength of important infrastructure members, construct more secure containment buildings which is important for the safety of nuclear power plant, reduce the section and reinforcement ratios in reinforced concrete structural members. In this regard, in the concrete technology in order to provide the above mentioned composite properties, the significance of fiber usage has increased. It was found from studies made that it is possible to produce more developed composites using hybrid fiber having different properties with single or different fiber combinations. In this paper, the significance of the use of fiber for producing the cementitious composite, fiber types and the using forms (single or hybrid) and the effects of micro and macro fiber types on the engineering properties of the hybrid fiber reinforced composites are investigated. Finally, at construction sector the use of hybrid reinforced composites has gained great importance due to the formation of multiple crack and high tensile strength.
