Abstract:

Thermal Integrity Profiling (TIP) measures the temperature of concrete along the length of drilled-shaft reinforcing cages to identify potential defects. The heat generated from hydration of cement within the drilled shaft is captured by wired sensors affixed to the cage and recorded by small data loggers at the ground surface. Areas of lower temperature indicate potential concrete defects within the drilled shaft. TIP’s sensitivity to defects outside the reinforcing cage make it an appealing alternative to Crosshole Sonic Logging (CSL), whose geophysical measurements only capture defects within the cage and often return false positives. This research was conducted to evaluate the effectiveness of TIP and its potential to serve as an alternative to CSL.
