Abstract EN
In the framework of strengthening and rehabilitation of concrete structures, the application of carbon fiber reinforced polymers (CFRP) is considered one of the effective techniques.
It was noticed that the interfacial debonding of CFRP is the most common mode of failure.
The last two decades had witnessed the innovation of extra ductile engineered cementitious composites )ECC).
Combinations between both ECC and CFRP are still limited.
Yet, this research focuses on the contact performance between ECC and CFRP as well as comparing it with corresponding cases with normal concrete substrate.
The induced interfacial stresses were investigated for each case.
The effect of CFRP thickness was also examined.
The study included the examination of thirteen beams equally made of ECC and plain concrete.
The specimens were destructively examined in a four point bending test.
The results show that the contact between ECC and CFRP was better than between concrete and CFRP ; however, the efficiency of strengthening was higher in case of concrete beams.
Moreover, the undesirable interfacial debonding failure mode was not observed in case of ECC.
The research ended-up with a recommendation of using ECC to replace the inferior layer in the deteriorated concrete members before strengthening with CFRP.
