“…These increases are not valid in the case of the smooth fibers. It is well known that the fiber-matrix bond strength increases by an improving in mechanical properties of cement based composites matrix [9][10][11][12][13][14][15][16]. On the other hand, pozzolanic reaction between the metakaolin and Ca(OH)2 which exists in the fiber-matrix transition zone (Fig.…”

“…1 The interface of steel fiber and cement based matrix Generally, it can be summarized from many researches that the pull-out behavior depends on both matrix and fiber characteristics. The mechanical properties of matrix, curing conditions, incorporation of mineral additives, and durability problems can affect the fiber-matrix bond characteristics [10][11][12][13]. Furthermore, the effect of steel fiber morphology, type and embedment length and fiber type on fiber-matrix bond characteristics has been investigated by many researchers [10][11][12][14][15][16].…”

SIFCON (Slurry Infiltrated Fiber Concrete) can be described as a special type of cement based composite produced with fiber volume fraction values between 5 to 30%. As a result of superior mechanical properties such as compressive, tensile, shear and flexural strengths with extraordinary toughness values, SIFCON can be used in in industrial floors, repair and reinforcement works and military applications such as anti-missile hangers. Mechanical properties of fiber reinforced cement based composites are dramatically influenced by steel fiber-matrix bond characteristics. Many parameters such as fiber type and geometry, matrix strength, curing conditions and properties of fiber-matrix interface affect the fibermatrix bond characteristics. The density of this zone can be increased with supplementary cementitious materials such as metakaolin. In this study the effect of metakaolin and end type of steel fiber on bond characteristics has been investigated. The fiber-matrix bond characteristics were determined by applying single-fiber pull-out test. Utilization of metakaolin has improved the compressive strength and fibermatrix bond characteristics. In addition, hooked-end fiber has a better performance compared to the smooth fiber.

“…to fiber reinforcement of concrete is determined by the bonding mechanism between the fibers and the concrete, including fiber bridging, fiber de-bonding, fiber pullout and fiber fracture when cracks occur [16][17][18][19][20][21][22][23]. The bond characteristics are influenced by a variety of factors, such as the morphological shape and length of the reinforcing fiber, the surface property, the interface between the concrete and the reinforcing fiber in addition to the strength of the concrete [22,23].…”

“…The first is mechanical improvement using fibers having crimped, hooked and twisted shapes [16,22,23]. The second is chemical treatment to improve the hydrophilicity of the fiber surface and thereby, improve compatibility with the concrete [16][17][18][19][20][21][22][23]. As reinforcement fibers, mixed polyolefin macro synthetic fibers, natural Jute fibers and PVA (polyvinyl alcohol) fibers were evaluated in terms of mechanical characteristics, chloride ion penetration properties and durability.…”

This study evaluated the effects of reinforcement fibers on the mechanical characteristics, chloride ion penetration properties and abrasion resistance of roller-compacted latex-modified fiber-reinforced rapid-hardening-cement concrete (RCLMFRRHCC) for use in the emergency repair of concrete pavements. The reinforcement fibers tested included macro synthetic fibers (a structural fiber) as well as PVA (polyvinyl alcohol) and natural Jute fibers (non-structural fibers). In the experiment, compressive strength, flexural strength, splitting tensile strength, chloride ion penetrating properties, abrasion resistance tests and impact resistance tests were performed. Test results were compared with traffic open standards of concrete for concrete pavement emergency repair. RCLMFRRHCC satisfied all traffic open standards for concrete emergency repair. Mixes with reinforcement fibers showed superior results to the mix without, in terms of compressive strength, flexural strength, splitting tensile strength, chloride ion penetration resistance, abrasion resistance and impact resistance. With regard to the reinforcement fibers, the compressive strength, flexural strength, splitting tensile strength, and impact resistance of the mix with macro synthetic fiber showed improved results as a structural fiber compared to mixes containing natural jute and PVA fibers, namely the non-structural fibers. However, using the reinforcement fiber type had little effect on chloride ion penetration resistance or abrasion resistance. Thus, the addition of reinforcement fibers was effective in improving the performance of RCLMFRRHCC. The use of macro synthetic fibers improved the mechanical characteristics of concrete.
