description abstract | Measuring the thickness of concrete elements in the field can be challenging. In many cases, such measurements must be made from one side due to a lack of access to the opposite face. One technique commonly implemented in these situations is the impact echo method, which requires advance knowledge of the compression, or P wave, velocity through the concrete at the point of interest. Common practice is to measure the near surface P-wave velocity at that point and then use this velocity to represent the through thickness P-wave velocity in the calculation of thickness. However, the relationship between near surface P-wave velocities and through thickness P-wave velocities can vary significantly under different exposure conditions. Using near surface P-wave velocity to represent through thickness P-wave velocity is not necessarily a valid assumption and should only be done when further information is available to substantiate the relationship. It is possible to detect damage due to sulfate attack in concrete specimens using P-wave velocity measurements, though actual identification of the nature of that damage is not feasible. | |
