Abstract

The main purpose to use ultrasonic pulse echo techniques for concrete are the following testing B;problems:
  • Injections faults in tendon ducts because they lead to a loss of the basic protection of the tendon steel and can result in corrosion damage

  • Compaction faults or honeycombing because they reduce the concrete strength. They influence the static stability beginning from a diameter of about 50 mm.
