Numerical analysis of reinforced concrete beam subject to pitting corrosion
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2021)
Chloride induced corrosion of reinforcing steel evaluated by concrete resistivity measurements
(Pergamon-Elsevier Science Ltd, 2004-10)
The chloride threshold (ClTH) concentration for rebar corrosion initiation has received extensive attention over the last years. The chloride threshold concentration depends on several factors involving concrete composition ...
Chloride-induced corrosion in reinforced concrete and fiber reinforced concrete elements under tensile service loads
(Elsevier, 2021-11)
Corrosion of rebars is one of the main issues affecting the service life of Reinforced Concrete (RC) structures. It is well-known that the use of fibers enhances the mechanical behavior of RC structures at both Serviceability ...
Carbon steel passivity examined in alkaline solutions: the effect of chloride and nitrite ions
(Pergamon-Elsevier Science Ltd, 2008-06-09)
The effect of chloride and nitrite ions on the passivity of steel in alkaline solutions was investigated. Four nitrite dosages were tested, resulting in various nitrite/chloride ratios. The behavior of steel was evaluated ...
Oxyanions as inhibitors of chloride-induced crevice corrosion of Alloy 22
(Elsevier, 2013-03)
Oxyanions were tested as inhibitors of the chloride-induced crevice corrosion of Alloy 22, at 90 °C. Nitrate was the most efficient inhibitor showing RCRIT = 0.2 for the two tested chloride concentrations. Sulphate showed ...
Effect of temperature on the crevice corrosion of nickel alloys containing chromium and molybdenum
(Electrochemical Society, 2015-03)
Chloride-induced crevice corrosion of alloys 625, C-22, C-22HS and HYBRID-BC1 was studied at different temperatures. Crevice corrosion occurred tens of degrees below the reported critical crevice temperatures obtained ...
Nitrite corrosion inhibition in chloride-rich electrolytes correlated to the electrical properties of surface films on carbon steel
(Elsevier, 2019-12)
The electronic properties and the composition of surface films grown in pore simulating solutions are studied using various electrochemical and surface techniques and then correlated to the inhibiting efficiency of nitrite ...
Electrochemical Behavior Of An Al-fe-ni Alloy Affected By Nano-sized Intermetallic Particles
(NATL ASSOC CORROSION ENGHOUSTON, 2015)
Evaluation and comparison of traditional methods and Electron Probe Micro Analysis (EPMA) to determine the chloride ingress perpendicular to cracks in self-healing concrete
(Elsevier, 2019-12)
The appearance of cracks in reinforced concrete structures accelerates the penetration of aggressive substances such as chloride ions into the concrete matrix. This leads to durability problems due to the accelerated onset ...
