“…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.…”

“…The abrasion resistance of SFRC is often related to toughness, which can be expressed in terms of flexural and compressive resistance [31,32,33]. Steel fibers, indeed, can reduce the porosity of the material and increase the adhesion between the different components of the SFRC material matrix.…”

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.

“…There was an obvious uneven distribution of the cement mortar, aggregates on surface and in the internal parts of concrete, and certain differences in the cement mortar thicknesses, which led to an uneven damage failure topography following the wind-sand erosion, as well as a weak wind-sand erosion resistance in the cement mortar. Also, the aggregates displayed strong wind-sand erosion resistance (Grdic et al 2012;Millman and Giancaspro 2015).…”

The study simulated the Aeolian sand concrete damage process under wind-sand erosion using a sand-bearing wind-sand erosion test device. Then, different wind parameters were selected to study their damage failure influences on Aeolian sand concrete surfaces, and an orthogonal test was carried out for three factors: wind speed, sand carrying capacity, and angle of attack. The significant level and variance contribution rate of the angles of attack were the largest. The test results indicated that the damage failure arising from wind-sand erosion could be divided into three stages: the accelerated development stage, attenuation stage, and stabilization stage. During the accelerated development stage, the damage failure of the concrete surfaces was found to be relatively large, and obvious erosion pits were produced following the erosion. With the increases in action times, the process gradually developed into the attenuation stage, and then finally into the stability stage. The test results revealed that the damage failure of the Aeolian sand concrete surfaces which arose from the sand flow with 200 to 300 μm diameter sand was relatively serious.

“…This trend was similar with the result of the tests above. The calculated abrasion weight loss of each PAN fiber reinforced concrete was 18.0, 16.3, 12.9, 14.7 and 15.9 g, respectively 24 . Compared to reference specimen, the abrasion weight loss of PAN fiber reinforced concrete specimens were lower by 9.4%, 28.3%, 18.3% and 11.7%, respectively.…”
