Performance of Organic Zinc-Rich Paint (ZRP) Coating Anode in Self-Powered Cement-Based Battery

Impressed current cathodic protection (ICCP) system is a well-known method to stop further corrosion in reinforced concrete (RC) structures which require an inert anode, a monitoring system, and a continuous direct current (DC) power supply.

總結:Impressed current cathodic protection (ICCP) system is a well-known method to stop further corrosion in reinforced concrete (RC) structures which require an inert anode, a monitoring system, and a continuous direct current (DC) power supply. However, a continuous DC power supply can cause high energy consumption which is non-environmentally friendly for long-term protection. Previously, cement-based battery was introduced for low power operation systems, but the effectiveness of anode used is reduced over time. Therefore, this paper presents the use of steel plates incorporated with different layers of organic zinc-rich paint (ZRP) as anode material, copper as cathode embedded in the cement-based electrolyte as a potential sustainable green energy for the ICCP system. The voltage, current discharge, and temperature from three different coating layers (one layer – ZRP(I), two layers – ZRP(II), and three layers – ZRP(III) were measured to evaluate the performance, and results were compared with previous cement-based battery design. The finding indicates that ZRP(I) produced the highest resistor-loaded peak current of 6.70 mA and longevity over 28 days compared to ZRP(II) and ZRP(III) anode. It is also found that when current discharge is increased, the internal temperature of the cement-based battery is also increased © 2021 College of Engineering, Universiti Teknologi MARA (UiTM), Malaysia
