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.

Assessment of Thermal Damage in Hybrid Fiber-Reinforced Concrete

Journal of Materials in Civil Engineering, 2010
Three-point bending tests on high-strength concrete specimens after exposure to high temperatures are presented, with a detailed evaluation of process zone size. The variables considered for the high-strength concrete were the types of fiber reinforcement: steel microfibers, polypropylene microfibers, and a hybrid combination of steel and polypropylene

Research on Hybrid Fiber Reinforced Concrete Lining Segments

Key Engineering Materials, 2018
Numerous cases on tunnel fires emphasized the importance of fire protection of tunnel lining and indicated that fire may cause severe damages to tunnel lining in term of concrete spalling, reduction of physical-mechanical characteristics and load bearing capacity. Hybrid Fiber Reinforced Concrete (HFRC) as a new type of composite building materials has

Experimental Investigation of the Fracture of Hybrid-Fiber-Reinforced Concrete

Mechanics of Composite Materials, 2015
The effects of polypropylene fibers on the fracture of concrete and steel-fiber-reinforced concrete (SFRC) are studied. Properties of the composites were investigated by conducting four-point bending tests. The experimental data obtained showed a good overall improvement in SFRC properties with addition of polypropylene fibers.

Hybrid fiber reinforced concrete : fiber synergy in very high strength concrete

2009
Over the years we have been able to overcome the inherent weaknesses of concrete thereby making it more suitable for a wide variety of applications. One major development has been reinforcement by short randomly distributed fibers that remedy weaknesses of concrete such as low crack growth resistance, high shrinkage cracking, low durability, etc.

Creep behavior of fiber reinforced self consolidating concrete reinforced with hybrid fibers

2019
Creep and shrinkage properties of fiber reinforced self-consolidating concrete (FR-SCC) are still unknown and limited in research. Thus, comprehensive evaluation is required to determine these behaviors of FR-SCC and mechanical properties must be verified to determine effectiveness of this type of concrete in structural application.
