Assessing corrosion damage in reinforced concrete

1999-2-1  The acoustic emission (AE) behavior of reinforced concrete beams tested under flexural loading was investigated to characterize and identify the source of damage. This research was aimed at identifying the characteristic AE response associated with micro-crack development, localized crack propagation, corrosion, and debonding of the reinforcing steel.

Corrosion damage diagnosis of a reinforced concrete

2006-3-1  A detailed investigation of the chloride induced corrosion damage was performed on a 40 years old reinforced concrete beam exposed in marine environment. Visual observations, electrochemical measurements, carbonation depth, total chloride content were carried out. Half-cell potential measurements were used to locate corrosion areas.

DETECTION OF CORROSION-INDUCED DAMAGE IN

2019-6-10  This article examines the possibility of corrosion damage detection in reinforced concrete (here after RC) beams based on modal damping changes. Four RC beams were damaged artificially by inducing uniform and localized corrosions on the beams. Modal tests were performed on the test beams before and after t he corrosion damage s, and extracted modal parameters were compared with each

2016-4-14  Steel reinforcing bars will corrode freely when exposed to moisture andoxygen under ambient conditions. When steel is embedded in concretehowever the high alkalinity (pH of 12.5 or higher) stifles corrosion by theformation of a passive ferric oxide film on the steel surface. The ferricoxide layer forms a dense, impenetrable film that suppresses further cor-rosion by limiting the movement of cations and anions near the steel sur-face. This passive ferric oxide film on embedded reinforcement
