Simulation of Corrosion of Rebar in Concrete by Impressed Current Technique
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 5
Abstract
Marine structures are adversely affected by corrosion of rebars. In order to assess the structural health, prediction of the amount of mass loss of rebars is important. In this context, an experimental investigation was done to find a relationship between crack width and level of corrosion. An impressed current technique was employed to accelerate the corrosion process. The crack width was measured by image analysis. In this research, a linear relationship was found between the crack width and mass loss. 32 mg/cm2 corrosion level was found to be needed for the appearance of surface cracking.
