Passive wireless sensors for monitoring behavior of recycled aggregate concrete

The study aims at developing sustainable concrete materials for infrastructure applications, and sensor technology can be used to improve the performance of concrete infrastructure. For example, the use of recycled concrete aggregate can raise concern about shrinkage and volume stability. New sensor technology can contribute to the acceptance of recycled concrete because it provides capability to be embedded in concrete pavements and structures and can be monitored using wireless technology. Radio Frequency Identification (RFID) technology has emerged as a powerful option for many applications including construction materials handling and inventory management. RFID tags can be either active or passive. Active tags have external power sources, usually batteries. Passive RFID tags do not use batteries or wired connections, but instead acquire their power from the RF energy from the reader which is not physically connected. The reader creates a magnetic field that energizes circuitry in the tag. Recent advances have outfitted RFID tags with sensors that measure temperature, humidity and even strain. Passive tags equipped to measure a strain gage can be interrogated by RFID readers from a distance ranging up to 18” through air or through several inches of concrete according to preliminary tests. This project studies the feasibility of applying new RFID technology – particularly passive tag technology – to infrastructure projects that incorporate recycled concrete aggregates.
