“…Some other researchers investigated the effect of drop-height or the drop-weight using the flexural drop-weight impact test on beam specimens. Zhu et al [42] conducted flexural impact tests on glass fiber-reinforced beams. The drop-weight was approximately 13.6 kg, while different drop-heights of 50, 100, 200 and 250 mm were tested.…”

A B S T R A C TSteel fiber has become a proven material that can significantly alter the behavior of different types of concrete mixtures from brittle to more ductile ones. Rich literature is currently available on the mechanical properties of steel fiber-reinforced self-compacting concrete. However, the investigation of the impact resistance of this material to drop weight is still required to enrich the knowledge about its behavior under different loading conditions. An experimental work was conducted in this research to evaluate the performance of steel fiber-reinforced self-compacting concrete under repeated impact loading using the repeated blows test recommended by ACI 544-2R. The tests investigated the effect of drop weight and drop height in addition to fiber content. Straight microsteel fibers were incorporated in three volumetric contents of 0.5, 0.75 and 1.0% and were compared with a similar plain mixture. The test equipment was adjusted to conduct repeated impact loading from different dropheights and using different drop-weights. The adopted drop-heights were 450, 575 and 700 mm, while the adopted drop-weights were 4.5, 6.0 and 7.5 kg. The combination of the adopted drop-heights and weights composes four loading cases in addition to the standard loading case with a drop-weight and drop-height of 4.5 kg and 450 mm. The inclusion of micro steel fiber was found to significantly increase the impact resistance of selfcompacting concrete with percentage developments ranging from 150 to 860% compared to plain samples. The specimens tested under 4.5 kg and 450 mm drop weight and height exhibited the highest percentage improvement in impact resistance among the five loading cases. The results also showed that the impact ductility of fibrous specimens was up to 24% higher than that of plain specimens.

“…Also, the toughness is improved due to debonding and energy absorption. The energy absorption, proportional to the area under the curve, will thus improve for example the earth-quake resistance, impact resistance and the service life of dams [56][57][58][59]. By mixing in fibers and designing the material in such a way, the brittle behavior is minimized and the composite will show significant ductile strain-hardening behavior.…”

“…For beams' specimens, it's the cross-section and the orientation of the fabric. For beams' specimens, maximum flexural stress rises with the number of textile fiber layers, while in the case of plate the maximum flexural stress was decreased with increasing the number of textile fiber layers because of interlaminar shear failure [10]. The effect TRMs as a means of enhancing the bending strength of RC beams was investigated by Elsanadedy et al (2013).…”

Normal concrete is weak against tensile strength, has low ductility and also insignificant resistance to cracking. The addition of diverse types of fibers at specific proportions can enhance the mechanical properties as well as the durability. Discrete fiber, which is commonly used, have many disadvantages such as balling the fiber, random distribution, and limitation of the used Vf ratio. Based on this vision, a new technique was discovered, enhancing concrete by textile-fiber to avoid all the problems mentioned above. This paper presents all important consequence and conclusions obtained from previous studies on how to strengthen concrete with two-dimensional and three-dimensional textile-fibers, and focuses on the flexural behavior of concrete members. The results indicate that there was an improvement in flexural strength, deformation capacity, and toughness with different load conditions when using different types of textile-fiber. It was observed that the effect of textile-fibers would increase when this fiber was coated by epoxy. In TRC system, there is a significant impact on the number of textile-fiber layers used.
