Nondestructive elastic-wave tests of post-tensioned concrete girders in road bridge
The results of the nondestructive elastic-wave tests and the exposures verifying them have shown that there are voids in the grout filling the tendon sheaths, air voids between the tendons and air voids in the (uncompacted) concrete in the road bridge built in Poland in the 1960s. The Impact-Echo was found to be very helpful in detecting the defects. The test results were used to calculate the actual load-carrying capacity of the bridge and to determine the scope of repairs to the post-tensioned concrete girders. Thus the tests have contributed to an improvement in the durability and service safety of the bridge.
