“…H. Ghanem and Y. Obeid [18] investigated the effect of using SF on the rheological properties of SFRSCC. Mixes with different SF length, aspect ratio and shape (hooked end and double hooked end) were used.…”

“…The second reason for orientation of fibers is ""wall effect"", where it is not possible at a distance lower than half the length of the SF to find fibers perpendicular to a wall of mould [28]. Ghanem and Obeid [18] investigated the effect of SFs on compressive and flexural strength depending on the mixes details mentioned previously. The results showed that using of SFs improved compressive strength, and the increasing varied between 11% to 26% depending on the aspect ratio and the length of SFs.…”

In this literature review steel fibers reinforced self-compacting concrete properties in fresh and hardened states and factors effecting on them were studied. In spite of high workability of self- compacting concrete, using of steel fibers depending on their length, aspect ratio, shapes and volume fraction can cause detrimental effects on it. Using of steel fibers improves hardened properties especially flexural and post peak performance, and this improvement depends on how fibers can distribute and orientate in fresh state. The better hardened properties can obtain when fibers aligned and orientated in the direction parallel to tensile stress.

“…Mixtures exceeding 150 MPa of compressive strength had cement contents between 680 and 977 kg/m 3 . Another research [ 9] showed some mechanical investigation on RPC with around 650 kg/m 3 cement, 420 kg/m 3 GGBFS and 120 kg/m 3 silica fume. Incorporating limestone powder in RPC improved the hydration process at the early-age, producing denser particle packing, and improving mechanical properties [ 10].…”

El objetivo principal de esta investigación es desarrollar una mezcla optimizada de concreto de polvos reactivos (RPC) que contenga materiales cementícios suplementarios (SCM), como la escoria siderúrgica de arco eléctrico (EASF) y el polvo de vidrio reciclado (RGP) entre otros, utilizando el diseño factorial. Se calcularon diferentes regresiones polinómicas para predecir con precisión las variables respuesta (flujo estático y resistencia a compresión a distintas edades) en función de los factores considerados. A través de un algoritmo multiobjetivo, se determinó la mezcla que alcance la resistencia y flujo estático adecuados con un contenido mínimo de cemento. La verificación experimental de esta optimización matemática mostró que con 621 kg/m3 de cemento ASTM Tipo HE, y un contenido máximo de 100 kg/m3 de humo de sílice, se puede alcanzar una resistencia a compresión superior a los 150 MPa en un concreto, además, autocompactante.

“…SFRC that contains fibers with multiple hooked-end has better stress-transfer mechanisms and improved anchorage than that of single hooked-end (Venkateshwaran et al 2018). Ghanem and Obeid (2015) investigated the effect of steel fibers on the workability and material properties of self-compacting concrete, and the test results showed that fibers reduce workability, especially with long length fibers. Jongvivatsakul et al (2011) studied the steel fibers contribution for shear in RSF beams, and proposed the method including the use of tension softening curves to calculate the residual tensile stress of steel fibers transferred across the critical diagonal crack.…”

The objective of this research is to propose a simple and accurate prediction method for the shear capacity of reinforced concrete beams with steel fiber (RSF beams). Steel fiber reinforced concrete (SFRC) is being widely used nowadays, with the steel fibers added to the concrete to improve the tensile resistance. First, this research aims to investigate the material properties of SFRC in various concrete compressive strengths, shapes of steel fiber and volume fractions of steel fiber. In order to evaluate the shear capacity, several material properties, such as tension softening curves and fracture energy were investigated in the material tests. Second, four-point bending tests of RSF beams were conducted in order to investigate the shear capacity and diagonal crack pattern. Eight RSF beams with various concrete compressive strengths, volume fractions of steel fiber and stirrup ratios were fabricated and tested. The results revealed that the concrete compressive strength and steel fiber significantly affect the shear capacity of RSF beams. Finally, the shear equation for the RSF beams failing in a diagonal tension failure mode has been proposed by focusing on the residual tensile stress perpendicular to the critical diagonal crack at the failure condition.
