Verification of concrete placement in post-tensioned bridge box girders using a rapid nondestructive test method
In 2002, the authors participated in a program to evaluate concrete placement in bridge sections comprising post-tensioned box girders at an early stage in the construction of the Taiwan High-Speed Rail (THSR) project. Nondestructive, Impulse Response testing was used to locate and quantify deficiencies in the girder concrete including poor consolidation, internal voiding, and debonded repair patches. The testing also identified absence of prestressing in concrete repair areas that were made after post-tensioning. The NDT program was beneficial in assessing and quantifying these early concrete placement difficulties, both for cast- in-place and full-span precast girder construction.
