Cathodic corrosion protection (CP) is a cost‐effective option for maintenance of concrete structures. CP is an electrochemical method that can be used to reduce the corrosion rate to an acceptable level. Thus, service life of reinforced concrete can be increased considerably. In this work, carbon textiles with varying polymer impregnations, cross sections, and mesh widths have been used as CP anodes and have been tested for their durability. The main goal of this research is to determine the behavior of carbon textile under permanent anodic polarization while stored in saturated calcium hydroxide solution. The outcome will serve as a basis for further investigations in which textiles will be permanently polarized and tested after embedding in mortar.
Carbon textiles as anode material for cathodic corrosion protection (CP) have been used in several reinforced steel structures. However, experience with durability is limited. To date, various influencing factors have been discovered and systematic tests on different carbon textiles with different impregnation materials in various environmental media have been carried out and considered the degradation of the impregnation materials. In this work the boundary potentials are determined at which the impregnation and sizing is destroyed under anodic polarization and the damage mechanisms are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
