Abstract: Corrosion is the gradual degradation of the metal by chemical reaction with the environment. The service life of the structure is a major concern that depends on the cost involved in construction, maintenance, and repair works. This paper discusses the corrosion mechanism, factors influencing corrosion, corrosion monitoring techniques, and corrosion protection methods. The monitoring techniques include the Linear polarization method, Active monitoring using sensors, DAQ cards, impedance measurement using chips, etc. Prevention methods include an application of paints with various chemical compositions, cathodic protection inhibitors, the use of fiberreinforced polymer, etc. 
Keywords: Corrosion, Types of corrosion, Factors affecting corrosion, Active sensing, DAQ card, sensors, FRP, cathodic protection
