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 ...
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 ...

Nanoparticles Reinforcement for the Improved Strength and High-Temperature Wear Resistance of Mn-Cr Steel
(Springer, 2018-07-18)
Nanotechnologies offer tremendous potential when it comes to modifying the microstructure of steel through the incorporation of nanoparticles. While typical production methods for metal-matrix composites are difficult and ...
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 ...
Unexpected effect of citrate ions on the corrosion process of carbon steel in alkaline solutions
(Elsevier, 2017-08-24)
The effect of citrate ions on the passive film stability on carbon steel, at pH 13, was evaluated. The study involved cyclic voltammograms, potentiodynamic polarization curves, micro-Raman spectroscopy and weight-loss ...
