Corrosion effects on pullout behavior of hooked steel fibers in self-compacting concrete
(2016-01-01)
Fiber reinforced concrete structures are subjected to chloride and carbonation penetration that could initiate corrosion of steel fibers, with eventual pernicious consequences in terms of structural and durability performance. ...
Flexural performance of concrete beams reinforced with epoxy resin/glass and carbon fibers composites
(2021-01-01)
Factors such as project and execution errors, lack of maintenance and inspection, and increases in loading can cause deficiencies to reinforced concrete structures. In this regard, there is the necessity of the application ...
An experimental study of steel fiber-reinforced high-strength concrete slender columns under cyclic loading
(2012-08-10)
Structural engineers usually limit the use of HSC columns to seismic active zones because of their britle behavior in comparison with NSC, even though it presents advantages both in terms of mechanics and durability. A ...
Experimental characterization of the post-cracking response in Hybrid Steel/Polypropylene Fiber-Reinforced Concrete
(Elsevier, 2016-10)
This paper presents and discusses the results of experimental tests performed on concrete specimens internally reinforced with polypropylene and steel fibers. Specifically, samples of five mixtures (plus a reference plain ...
Fadiga em dormentes de concreto reforçados com fibras de aço
(2001-07-01)
A prestressed concrete monoblock railroad tie was designed to attend the characteristics of a Brazilian railroad track with 1,600 mm gauge and 320 kN axle load. Concrete ties specimens were manufactured without and with ...

Influence of fiber orientation on the behavior of fiber reinforced concrete slabs
(John Wiley & Sons Inc, 2021-06)
After several decades of research studies, design rules for fiber reinforced concrete (FRC) are now available for several structural elements. Starting from standard tests, it is possible to determine design parameters and ...
Electrochemical Assessment Of Steel Concrete Reinforced System Modified whit Natural Fiber for ITS Anticorrosion Protection
(64th Annual Meeting of the International Society of Electrochemistry- Sep. 2013 Qro. Mex s05-027, 2013-09-13)
The deterioration in the steel-concrete structures is mainly due to chloride contamination, which causes corrosion problems that occasionally leads its partial or total destruction. In this work we propose adding fibers ...
