Thermal Integrity Profiling

Thermal Integrity Profiling

20171030_130808

The Thermal Integrity Profiler (TIP) uses the heat generated by curing cement (hydration energy) to assess the quality of cast in place concrete foundations such as drilled shafts, bored, continuous flight augured and drilled displacement piles. TIP is usually completed within 48 hours of shaft installation – earlier than any ohter integrity evaluation cast in place concrete foundations.

The expected temperature at any location is dependent on the shaft diameter, mix design, time of measurement and distance to the centre of the shaft. TIP evaluates the concrete quality of the entire cross-section, including outside the reinforcing cage, and along the entire length, without maximum length limitations.

TIP RESULTS IN BRIEF
Regions that are COLDER THAN NORMAL – indicate necks or inclusions, or poor concrete quality
Regions that are WARMER THAN NORMAL – indicate bulges

CMR Tech uses the TIP Thermal Wire Cable System (ASTM 7949 Method B) which includes cables fitted with digital thermal sensors spaced every 305mm attached to the reinforcing cage prior to concreting. A Thermal Acquisition Port (TAP) is connected to every wire and automatically samples data throughout the temperature curing process. The temperature versus time history prior to the peak temperature is inspected to confirm uniform quality or spot potential anomalies.
