Corrosion Monitoring in Reinforced Concrete Structures by Impressed Current Technique Meenakshi Dixit and Ashok Kumar Gupta Abstract Steel reinforcement corrosion results in deterioration or even early collapse of reinforced concrete (RC) structures. Corrosion of reinforced steel is a serious issue of durability globally and remains the main focus of many research studies. The formation of cracks in concrete because of corrosion is a basic indicator showing the service limit of existing RC structure. The natural corrosion that occurs in steel reinforcement present in concrete is generally slow and takes a reasonably long time to start. So, various methods are preferred to enable or accelerate corro- sion for experimentation purposes for assessing the structural performance of RC specimens. This paper aims to review the various studies done on impressed current technique (ICT) for accelerating corrosion for the research point of view. This tech- nique presents a new angle to analyze the corrosion process of reinforced steel and facilitates to improve the numerical approach to study the corrosion-induced damages in structures. Keywords Corrosion · Reinforced concrete · Durability · Impressed current technique · Structural performance 1 Introduction Reinforced concrete is one of the most used construction materials [1–3]. One of the reasons why steel and concrete can work together is that good bond properties exist between these two materials [1]. The concrete being a heterogeneous material with different pore sizes permits aggressive agents to infiltrate into the concrete from the external surroundings and triggers the initiation of corrosion of steel bars after reaching its surface [4]. The corrosion of steel bars embedded in concrete is the most problematic issue that leads to its deterioration and ultimately shortens their M. Dixit (B ) · A. K.
