The paper deals with the results of an experimental program aimed at investigating the bond behavior of different types of Externally Bonded Carbon (EBR) plates. The activity falls within an international Round Robin Test organized by the fib TG 9.3. The same experimental program has been carried out simultaneously by the Laboratory of Structural Testing of the University of Bologna and the Laboratory of Structural Engineering of the University of Naples Federico II and consisted in 18 bond tests on concrete prisms strengthened with EBR carbon plates. Each lab performed the bond tests according to two different set-ups for the Monotonic Single Shear Tests (SST). The comparisons of the results of tests carried out by the two laboratories according to the same loading scheme, but realized with different experimental set-ups are aimed to investigate the influence of the testing procedure on the bond strength. The results are analyzed in terms of debonding load, failure modes and strain distribution.
