Corrosion assessment study using half cell potentiometer with different electrodes

World has come across various natural transformations and process which has its own pros and cons. Metals are widely used in the world for multiple reasons in which the materials are hard, lustrous, malleable used commonly in construction industry, technology development, medicinal products, space researches etc. A natural transformation process caused by essential phenomena like water, air and gaseous things which leads to an electro-chemical action called corrosion. The corrosion causes cautious destruction to the metals by attacking it through various chemical and electro-chemical processes. Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expansion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling. This report aims to access and determine the range of corrosion in a reinforced structure by half-cell potentiometer with different reference electrode to get the accuracy between the them, impressed current technique is used for acceleration of corrosion. The experimental study includes the compressive strength, flexural strength and tensile strength tests are also conducted for the designed concrete sample in the grade of M20.
