... for the determination of the chloride threshold of stainless steel Abstract Reinforced concrete infrastructure frequently requires maintenance and repair before the designed service life is reached despite the fact that the structure complied with the durability design rules at the time of construction. A major...

... of the quality control plan to give account of the CP and anode circuit resistance. ICCP RESULTS Protection criteria The following criteria are used for assessing the effectiveness of the cathodic protection systems of reinforced concrete structures. ¹¹ An instant-off potential more negative than...

...The corrosion assessment of structures in reinforced concrete (RC) will become more and more important in the coming decades. This is because our infrastructure is constantly ageing, which increases the risk for gradual deterioration. The age distribution of civil engineering structures in most...

... and corrosion propagation are elucidated and correlated with the premature corrosion deterioration. Reinforced Concrete Deterioration Materials Performance Environment Infrastructure CONDITION ASSESSMENT An evaluation of the concrete transport properties was performed using chloride penetration data...

... output of conventional non-interactive models, encouraging expanding the approach to more realistic 3D systems. Here a simplified realization of a reinforced concrete slab is presented for a chloride-induced corrosion scenario, as an initial step toward incorporating this IM approach in practical 3D...

.... As a result, the C_crit values reported in the literature vary over a large range ¹³ . Abstract The fundamental reason behind the corrosion-related deteriorations in reinforced concrete structures is the brittleness of conventional concrete, which makes the unreinforced cover prone...

...Low alloy steel bar Reinforced concrete Tropical marine atmosphere XRD EIS INTRODUCTION A large number of reinforced concrete structures have been used in many fields of offshore engineering facilities, such as sea-crossing bridges, harbour wharfs and oil production platforms ^{1 , 2}...

... the steel and eliminated the risk of short circuits. The anode was installed in vertical runs down the length of the zone at 300 mm spacing where it is bonded at each end via Titanium conductor bar (also housed in isolating spacer rail). Abstract Marine reinforced concrete structures are expected to suffer...

... cathodic protection (ICCP) is one corrosion management approach adopted by the Port of Newcastle (PoN) for their reinforced concrete wharves. The Port’s West Basin 3 wharf, has ICCP systems installed to select substructure concrete elements (beams). The West Basin 3 ICCP system to the front beam soffit...

... of these bridges were constructed using steel reinforced concrete and are supported by precast pilings situated in saltwater, so for this reason, cathodic protection is a necessary strategy for controlling the effects of saltwater induced corrosion. Toward the early 1980s, the Florida Department of Transportation...

... during and after casting of concrete. After 48 hours of casting, the concrete blocks were demoulded and cured for one month. Abstract Chloride-induced rebar corrosion is one of the main causes of premature deterioration of reinforced concrete (RC) structures in marine environment. This study aims...

...Aural Testing of concrete surfaces was performed using an appropriately weighted hammer. This survey was used to determine areas of concrete delamination by noting differences in aural feedback. Abstract Reinforced concrete towers in a water reservoir contain gates and the equipment to control...

... maintenance periods which has accelerated deterioration of reinforced concrete bridge structures. The cause is due to the now well recognized chloride induced corrosion of the plain (black) reinforcing steel, resulting in spalling of the concrete cover. A Monte Carlo probability analysis was performed...

... with the bars immersed in a simulated pore solution with and without contamination by chloride ions. Tests using 304 SS were conducted as a reference. stainless steel reinforced concrete rebar marine environment INTRODUCTION The duplex stainless steels (DSSs) are composed of Fe, Cr and Ni with a ferritic...

... increases logarithmically with an increase in the corrosion-induced area loss of steel bars. Reinforced Concrete Corrosion Chloride Probabilistic Modeling Crack Width INTRODUCTION Reinforced concrete (RC) structures often suffer from damage due to reinforcement steel corrosion that is caused by either...

...Abstract Corrosion of steel reinforcement is one of the main causes of premature deterioration in reinforced concrete (RC) structures. It causes concrete cover cracking, degrades the steel/concrete bond strength, reduces the cross section of steel bars, and consequently reduces the carrying...

... are spaced at 5 inches (12.7 cm) on center and No. 8 circumferential bars are spaced at 6 inches (15.2 cm). The nominal cover to reinforcement is 2 inches (5.1 cm). The shell is supported by 32 precast reinforced concrete X-columns that are approximately 60 feet (18.3 m) tall with a 20 by 33 inch (50.8...

...Abstract In recent years the use of sacrificial anodes for cathodic protection in reinforced concrete structures has increased reflecting ease of installation, low maintenance requirements as well as desirability in prestressed concrete structures where the naturally controlled protection...

...Abstract The good performance of galvanic cathodic protection (CP) systems are well documented and recognized in the mitigation of corrosion related damage of steel reinforced concrete (RC) structures located in marine environments. However, in order to obtain suitable performance from these CP...

... The corrosion of reinforcing steel in concrete is considered the major cause of deterioration on steel reinforced concrete structures located in marine environments. Millions of dollars are spent every year in repairing the damaged structures to assure their safe use. This deterioration is most evident...
