Performance assessment of specialist conductive paint for cathodic protection of steel in reinforced concrete structures

Potential and current distribution across different layers of reinforcement in reinforced concrete cathodic protection system- A numerical study

“…Zinc rich paint (ZRP) as the conductive coating was used as an anode material and applied at the top surface of concrete having dry film thickness of 300 µm. The anode properties have already been published by authors [4]. A total of 3 beams were cast and average result of them is presented.…”

“…Cathodic protection (CP) is one of the most widely used and accepted technique to protect chloride induced corrosion in reinforced concrete [1,2]. CP is dependent on delivering enough uniform current to the reinforcement to protect it from corrosion [3][4][5]. However, the magnitude of protection achieved is dependent on a number of parameters and boundary conditions such as anode type, nature of the concrete component, concrete porosity, water and chloride content, concrete resistivity and geometrical arrangement [6][7][8].…”

Comparative Study on the Corrosion Resistance of Inorganic Zinc-Rich Coating and Thermal-Spray Zinc Coating

“…The industry practice has proved that the life of thermal spraying zinc coating can reach more than 20 years on the basis of guaranteeing the reliability of the coating [6,7]. It is a kind of heavy anticorrosive coating with excellent performance, and its life period is widely recognized in the field of heavy anticorrosive coating [8]. As a new coating technology, the inorganic zinc-rich coating has better corrosion resistance performance than the thermal spraying zinc coating in laboratory evaluation system [9].…”

Performance assessment of cathodically protected reinforced concrete structure based on alternative performance criterion: a case study

“…Cathodic protection (CP), an electrochemical technique, has long track records to stop or mitigate corrosion of steel in various environments, including the steel reinforcement in chloride contaminated concrete [2][3][4][5]. Cathodic protection involves applying a negative potential to the metal to be protected via an external electric circuit (Impressed Current Cathodic Protection, ICCP) or by attaching a sacrificial anode (Sacrificial Cathodic Protection, SACP) which corrodes more readily to the metal (e.g.…”
