Optimization of a Hybrid-Fiber-Reinforced High-Strength Concrete

Mechanics of Composite Materials, 2016
The fracture performance of a high-strength concrete reinforced with steel fibers was studied. Tests of notched beams subjected to fracture in the three-point bend configuration were conducted in accordance with RILEM recommendations TC 162-TDF. The R-curve concepts based on load–CMOD responses and the RILEM criteria were used for the performance ...

MECHANICAL PROPERTIES OF HYBRID FIBER REINFORCED CONCRETE

, 2007
Fiber reinforcement is commonly used to provide toughness and ductility to brittle cementitious matrices. Reinforcement of concrete with a single type of fiber may improve the desired properties to a limited level. A composite can be termed as hybrid, if

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.
