Influence of steel fibers on the flexural performance of concrete incorporating recycled concrete aggregates and dune sand

, 2020
The flexural performance of steel fiber-reinforced concrete made with recycled concrete aggregates (RCA) and desert dune sand was investigated. Natural aggregates were replaced by 30, 70, and 100% RCA.

Influence of curing regime on properties of reactive powder concrete containing waste steel fibers

, 2020
Reactive powder concrete (RPC) has excellent mechanical properties and durability, but its excellent properties are mainly obtained by selecting materials (high cost) and complicated curing process.

Fatigue Resistance of Recycled Steel Fibers (Discarded Vehicle Tyre Steel Fibers) Concrete Pavement

2020
Concrete pavements are exposed to repetitive (cyclic traffic) loads throughout its lifespan resulting in the instigation of cracks. Propagation of cracks implies to permanent damage of rigid pavement owing to fatigue damage. From inception, cause of the creation of cracks in the rigid pavement is less resistance of the rigid pavement against bending ...

Dynamic performance enhancement of RC slabs by steel fibers vs. externally bonded GFRP sheets under impact loading

Engineering structures, 2020
Recently, to improve the dynamic behavior of Reinforced Concrete (RC) slabs under impact load, the methods of externally bonding Glass Fiber Reinforced Polymer (GFRP) sheets to slab and internally reinforcing concrete by steel fibers have been proposed ...

Effect of steel fibers with galvanized coatings on corrosion of steel bars embedded in UHPC

Composites Part B: Engineering, 2019
Ultra-high-performance concrete (UHPC) is widely accepted for its super-high durability. However, the corrosion performance of steel reinforcing bars embedded in UHPC and the improved protection of UHPC cover to steel bars are seldom studied. Furthermore,

Improvement of flexural and tensile strength of layered-casting UHPC with aligned steel fibers

, 2020
In order to further improve flexural and tensile strength as well as ductility of ultra-high performance concrete (UHPC), this research developed an improved device for casting layered UHPC with better alignment of the fiber. The effect of fiber content (

Achieving slip-hardening behavior of sanded straight steel fibers in ultra-high-performance concrete

, 2020
This study develops a slip-hardening straight steel fiber in ultra-high-performance concrete (UHPC). For this, a surface treatment using sandpaper with various grits was adopted in both parallel and perpendicular directions to the fiber axis.

Effect of Corroded Steel Fibers on Mechanical Behavior of Steel Fiber Reinforced Concrete

2020
This paper presents the exposure test results of Steel Fiber Reinforced Concrete (SFRC) beams having crack width of 0.2 mm for 3 months, 1 year and 2 years. By flexural loading test, initial stiffness of the exposed SFRC beams was decreased with increasing of exposure period. And corrosion of steel fibers themselves was observed at crack surface.

Partially Steel-Fiber Reinforced Mortar

Journal of the Structural Division, 1979
Flexural members that are reinforced by steel fibers for only a portion of their depth, referred to as being partially reinforced, can have strengths and ductilities equal to those of members reinforced for the full depth and at a considerable saving in costs. Beams 3-in. (76-mm) deep, reinforced with 1.5% by volume of 0.5-in. x 0.0058-in.
