“…To effectively apply an ICCP technique in practice, it is critical to choose an anode material with a high-performance capacity in a concrete system, especially for high-resistivity reinforced concrete [ 4 ]. Current research on anode materials, optimizing for polarization behavior and cost, generally focuses on thermally sprayed zinc [ 5 ], titanium anodes [ 6 , 7 ], titanium mesh anodes [ 8 ], coating-overlay anodes [ 9 ], and conductive paints [ 10 ]. However, they have several drawbacks and are not well adopted in fields.…”

Carbon fiber-reinforced polymer (CFRP) is recognized as a promising anode material to prevent steel corrosion in reinforced concrete. However, the electrochemical performance of CFRP itself is unclear. This paper focuses on the understanding of electrochemical and mechanical properties of CFRP in an oxygen evolution environment by conducting accelerated polarization tests. Different amounts of current density were applied in polarization tests with various test durations, and feeding voltage and potential were measured. Afterwards, tensile tests were carried out to investigate the failure modes for the post-polarization CFRP specimens. Results show that CFRP specimens had two typical tensile-failure modes and had a stable anodic performance in an oxygen evolution environment. As such, CFRP can be potentially used as an anode material for impressed current cathodic protection (ICCP) of reinforced concrete structures, besides the fact that CFRP can strengthen the structural properties of reinforced concrete.

“…However, the major challenge is throwing power, which is a distance that current can be supplied. In many studies, the SACP system showed that the distance is limited to a few ten centimeters, which is mainly dependent on the concrete resistivity [8]. Thus, it is difficult to protect entire structure by menas of the SACP since the structure tends to be more larger and complex.…”

This paper represents the experimental studies on the throwing power of sacrificial anode cathodic protection system applied to reinforced concrete piles in salt water condition by means of zinc anodes. Many previous studies show the effectiveness of sacrificial anode cathodic protection system, however, the major problem of sacrificial anode cathodic protection system is limited a distance to the point reaching protection current from the anode in high resistivity environments such as concrete, etc. In case of concrete pile in sea water condition, it should be combined submerged zone, tidal zone, splash zone, and atmospheric zone. In this study, the cathodic protection current by zinc sacrificial anodes was limited to scores of centimeters above the water line with tidal, depending on the concrete resistivity. Experimental tests were carried out on pile type reinforced concrete specimens with the change of water level. The test factors were corrosion and protection potential, current, and 4 hour depolarization potential. As a result of tests, cathodic protection current by zinc sacrificial anode was influenced up to about 10cm above the water line, and high resistivity areas such as atmospheric zone could not be protected with this system.

“…Therefore, this study focuses on the relationship between anode types for ICCP system and CP performance on reinforced concrete. Comparitive study with laboratory experiments was carried out on reinforced concrete specimens with 3 different types of commercial anodes for the ICCP system to compare the performance of each anode [8,9,10].…”

This paper presents the results of the effects of anodes for impressed current cathodic protection (ICCP) system on reinforced concrete. Experimental tests were carried out on reinforced concrete specimens with 3 different kinds of commercial anodes that are used for ICCP in order for comparative study. Results have shown that the type of anodes is irrelevant to the effectiveness of cathodic protection. CP current similarly flowed to the anodes regardless of anode types in seawater condition. In addition, current was much higher in seawater condition than freshwater and air condition. The results show that titanium rod anode was slightly more effective in fresh water, and titanium mesh anode showed a better performance in atmospheric condition. The potential drop caused by concrete resistance in atmospheric condition should be considered at depolarization potential measurement.
