Impact-echo testing of steel cable ducts for injection grouting quality
The quality of the injection with a cement-based, cement slurry in a steel cable duct, 80 mm in diameter, containing 8 tendons and positioned at a depth between 105 mm to 190 mm in a slab with varying thickness was tested successfully with impact-echo. Properly applied, the impact-echo system is a powerful diagnostic tool for detection of the injection quality of steel cable ducts. The term 'properly applied' means that the basic limitations of the system have to be taken into account, the proper homework has to be done prior to the testing, the proper hardware selected and the test results have to be verified in a pilot study prior to conducting the main testing program. For testing of injection of cable ducts it is important to conduct the impact-echo testing above the centerline of the duct. Should the centerline not be easily and reliably identified on the project, the only solution is to locate the duct and its depth by means of radar (GPR) prior to testing with impact-echo.
