Development of Tendon Imaging Sensor

Based on the background statement stated above, an investigation is proposed with the following objectives: (1) Develop for field application a non-intrusive method to image strand position inside the cross section of external post tensioned tendons. (2) Use imaged strand data to enable improved use of supplemental technologies (to be selected among electromagnetic, acoustic, electrochemical, thermal or other suitable methods) for detection of grouting anomalies and their imaging in the tendon cross section. Produce a laboratory prototype.
