ABSTRACT
Radio Frequency Identification (RFID) is a method of uniquely identifying an object by means of wireless radio transmission. This technology has grown quickly in recent years. RFID methods can be implemented to efficiently inspect newly constructed concrete structures. Our wireless corrosion sensor was developed to predict the period when corrosion of a steel bar encased in concrete occurs. This is a nondestructive monitoring method. Multiple sensor specimens were cast and paired with identical steel specimens. These specimens were then subject to an environment of excess chloride ions. After the experiments, we can confirm that the sensor detects corrosion as the internal resistance of the sensor increases. Results confirmed the sensors do not corrode while verifying the structural integrity of the steel reinforced concrete. In addition, these sensors have already been implemented in newly constructed and renovated structures.
