Ultra High Performance Concrete Reinforced with Short Steel and Carbon Fibers

Abstract: Fibers are usually used in High Performance Concrete with a purpose to increase bending strength and ductility. Important properties are the peak value of bearing stress (strength) and post-cracking behavior of bended element. In the framework of an experimental part, Ultra High Performance mix compositions were prepared using intensive mixer. Short steel fibers and carbon micro fibers in amount of 1% by volume, as well as its combination were used for cement matrix reinforcing. Results of compressive and bend… Show more

“…Impressive progress has been made in the construction industry since the introduction of the reinforced concrete. In most reinforced concrete constructions, concrete is strengthened with the bars made of different materials [5][6][7][8][9][10][11]. Plain concrete without additional reinforcement is frangible.…”

“…While steel reinforcement is the dominant choice in the construction industry, there are some concerns about corrosion 15 . Nonmetallic fibers, on the other hand, show better performance when exposed to aggressive chemicals and can be used for making lightweight, high strength, and workable concrete 16 . Nonmetallic fibers in the form of short fibers can be categorized as short carbon fibers, carbon nanotubes, inorganic fibers such as glass and basalt, natural fibers such as wool and bamboo, and synthetic polymer fibers such as polypropylene and polyethylene 17 …”

“…This problem becomes more pronounced with increased dosage of the fibres. All mentioned fibres are split or torn in shorter pieces, when mixed with concrete in high-speed mixers [7]. Fibres from E-and S-glass are chemically unstable in alkali environments.…”
