Review on Behavior of Hybrid Fiber-Reinforced Concrete

2020
A review about attainment for hybrid fiber-reinforced concrete (HFRC) by adding small fibers, it gives more efficient and here the combination of fibers with firm spacing and evenly dispersed fibers which will resist the fractures that extensively develops its properties.

Microfiber and Macrofiber Hybrid Fiber-Reinforced Concrete

Journal of Materials in Civil Engineering, 2005
To realize the potential of micro- and macrofiber blends in a concrete matrix, a concrete containing polyvinyl alcohol (PVA) or steel microfibers and steel macrofibers was designed using a mixture proportioning method that provides good workability in concretes containing microfibers.

Enhancing corrosion resistance of reinforced concrete structures with hybrid fiber reinforced concrete

Corrosion Science, 2015
Abstract Service loads well below the yield strength of steel reinforcing bars lead to cracking of reinforced concrete. This paper investigates whether the crack resistance of Hybrid Fiber Reinforced Concrete (HyFRC) reduces the corrosion rate of steel reinforcing bars in concrete after cyclic flexural loading.

Structural Performances of Concrete Beams with Hybrid (Fiber-Reinforced Polymer-Steel) Reinforcements

Journal of Composites for Construction, 2002
The paper analyzes the structural behavior of concrete beams reinforced with hybrid fiber-reinforced polymer (FRP)-steel reinforcements. The analysis refers to concrete beams reinforced with FRP rebars placed near the outer surface of the tensile zone, with low cover thickness values, and steel rebars placed at the inner level of the tensile zone, with

Behaviour of Concrete Beams Reinforced with Hybrid Fiber Reinforced Bars

Advanced Composite Materials, 2011
Due to the linear elastic behaviour of FRP bars, the flexural behaviour of FRP reinforced beams exhibits no ductility as occurs in the steel reinforced structures.

Performance of Hybrid Fiber Reinforced Concrete with Steel Fibers and Polypropylene Fibers

Civil Engineering and Urban Planning 2012, 2012
The geometrical size and modulus of fibers are the main factors influencing the mechanical performances of fiber reinforced concrete. The use of different type of fiber in a suitable combination may potentially improve the overall mechanical performances of concrete and result in performance synergy.

HYBRID FIBER REINFORCED CONCRETE

2007
This paper describes the mechanical performance of hybrid fiber concrete with a maximum fiber dosage of 0.75 Vol.%. Two types of fibers were used: short straight steel fibers and long hooked-end steel fibers. The concrete compressive strength (fc,cub150) varied between 55 and 65 MPa, dependent on the fiber mixture.
