A review of developments in cathodic protection systems for reinforced concrete structures
نویسندگان
چکیده
Cathodic protection is a corrosion management strategy for deteriorating reinforced concrete structures or it can be used as preventative measure in situations where may expected during the service life result of environmental exposure conditions. The technology has advanced over time. There are now number different systems that conveniently considered three categories, including impressed current cathodic (ICCP), hybrid (HCP), and galvanic (GCP). Asset owners need to choose which option use possibly without understanding sustainability, environmental, health safety, construction, technical, operational, monitoring aspects. Generally, agreed among engineers ICCP most powerful robust solution with widespread deterioration. HCP GCP also viable options, even aggressive environments future maintenance intervention. advantages disadvantages each system discussed detail. This paper explains why commonly accepted expectancy 50 75 years compared GCP, typically limited 15-30 years. details likely requirements, associated timescales, whole-life costs 100-year design analysed references sustainability. That includes discussion about presents lowest embodied carbon environments.

CATHODIC PROTECTION OF STEEL REINFORCED CONCRETE BY CONDUCTIVE EPOXY PAINTS IN MARINE ENVIRONMENTS
Anodes are critical component of cathodic protection systems. As part of this effort, three different anodes were tested in a cathodic protection system that was designed and constructed to prevent further corrosion of reinforced concrete. This anodic system includes an electrically conductive coating composition applied in fluid form over an outer surface of the concrete mix. The composition f...

Marine structures are one of the most important and susceptible facilities in Iran due to corrosion. The two methods of Cathodic Protection, namely, the cathodic protection with sacrificial anodes and cathodic protection using impressed current, are widely used for corrosion protection. According to the former, sacrificial anodes are installed at several points in the structure. Position of the...

متن کاملCorrosion Monitoring of Reinforced Concrete Structures - A Review
Reinforced concrete structures have the potential to be very durable and capable of withstanding a variety of adverse environmental conditions. However, failures in the structures do still occur as a result of premature reinforcement corrosion. The maintenance and repair of bridges and buildings for their safety requires effective inspection and monitoring techniques for assessing the reinforce...
