“…These relationships are almost the same trend as those presented in related previous studies conducted on both steel and polypropylene fibers [31,34]. The results, however, are given according to the abrasive speed, E R (g/min) and for a unique abrasion exposure time.…”

“…A survey of the literature reveals that a considerable amount of effort has been devoted to the study of the abrasion resistance of reinforced concrete with, however, different testing conditions (type of fibers, unique SF content, device, etc.) [31,32,33,34]. None of them, nevertheless, has underlined the importance of the SF volumetric content.…”

Abstract:Concrete brittle fracture and low tensile strength constitute an important durability problem, since they can lead to disastrous damage and failure of the reinforced concrete structures. The improvement of concrete mechanical properties by adding steel fibers to plain concrete is considered as an interesting solution to the problem. This work fits into the continuity of scientific contributions in the field of Steel Fiber Reinforcement Concrete (SFRC). It relies on an experimental study conducted to examine compressive, flexural and abrasion resistance of steel fiber reinforced concrete specimens. The used Steel Fibers (S.F) are curved steel elements with a length to diameter ratio equal to 67. Concrete is made of local materials. The steel fiber contents examined are 0.5%, 1% and 1.5%. The purpose of this research is to investigate the mechanical performances of steel fibers reinforced concrete regarding compressive strength, flexural strength, mechanical abrasion and ductility according to the specimen age. The experimental results show a significant improvement in the mechanical behavior of the SFRC specimens in comparison with plain concrete without reinforcement.

Concrete has low tensile strength and crack resistance. Its weaknesses could be enhanced with the addition of fiber. Polyethylene terephthalate (PET) fibers are generally used in concrete as discrete reinforcement in substitution of steel fiber. Fibers obtained by hand cutting of PET bottles are in the form of straight slit sheets, which impart weaker bonding in concrete matrix. The bonding of the fibers however may be improved by using other geometries such as flattened-end sheet pattern. So far, there are no guidelines for defining the geometry and dimensions of PET fibers. Therefore, this paper focuses on the use of fibers with different geometries and dimensions and investigates their effects on the mechanical properties of concrete. Test results show that geometry of fibers has a small effect on the workability of concrete. The use of smaller dimensions of fiber improves the workability. Enhancement in the strength and energy dissipation capacity of fiber concretes was observed from the use of flattened-end fibers of smaller dimensions. Furthermore, a higher ultrasonic pulse velocity value was observed for concrete made from smaller fibers as compared to fibers of larger dimensions.

“…Saikia and de Brito [11] determined the abrasion resistance of concrete containing shredded PET bottle waste as a partial replacement of natural aggregate using Böhme apparatus according to the DIN 52108. The effect of class F fly ash and coal bottom ash as partial substitutes for fine aggregate and cement on the abrasion resistance of concrete was investigated by Siddique's research team in accordance with Indian Standard IS 1237-1980 [12] [13] [14] [15] [16]. This method is comparable to ASTM C1138M [6] which qualitatively simulates the behaviour of swirling water containing suspended and transported solid objects that cause abrasion of hydraulic concrete structures.…”

The purpose of this study is to comparatively evaluate the wear resistance of concretes under abrasion rates. Five concrete mix proportions of a fixed water-cement ratio of 0.45 were considered in the study, but the constituent materials, age of concrete and exposure contact conditions were varied. The coarse aggregate type employed in the study was crushed granite. The compressive strength and abrasion resistance of concretes were tested between at ages 7 to 70 days and 100 -500 revolutions of abrasion wheels respectively. The study revealed that the compressive strength and abrasion resistance had the optimal performance when the coarse aggregate content was 45% and the worst performance when the fine aggregate content was 28.7% of the total weight of concrete constituents. There was a remarkable loss of concrete particles to wear between 200 revs and 300 revs of abrasion wheel contact. Concrete grade in excess of 60 N/mm 2 is required to resist abrasion beyond 200 revolutions of abrasion wheel contact on concrete specimens. Concretes investigated also showed weak resistance to deep abrasion at and above 300 revolutions of abrasion wheel contact.
