Evaluating CFRP-Concrete Bond Performance
The purpose of this paper is to present the results of non-destructive testing (NDT) on CFRP-structural systems applied to RC (reinforced concrete) highway bridges in North Macedonia on the M2 and one bridge in Slovenia on the E57. The NDT procedure performed impact tests on CFRP plates applied to bridge structural members to determine CFRP-concrete bond performance: bonded vs de-bonded. Using the impact-echo technique, the NDT machine produced acoustic emissions with specific frequencies and sinusoidal waveforms indicating the CFRP-concrete bond condition. The NDT procedure used for the field investigation in Oct 2019, on 12 of the 17 CFRP-retrofitted bridges, confirmed the CFRP systems applied in 2001 remain fully bonded to the bridge structural members. The bridge section tested in Slovenia found the CFRP plates fully bonded 21 years after installation.
