dc.descriptionThis work aims at assessing the durability of the CFRP-concrete bond exposed to different outdoor ageing environments for a period of three years.por
dc.description.abstractCarbon Fibre Reinforced Polymer (CFRP) composites have been shown to possess desirable properties for strengthening of reinforced concrete (RC) structures. The application of CFRP composites is mainly through Externally Bonded Reinforcement (EBR) or Near Surface-Mounted (NSM) techniques. The main objective of the present work was to provide insights on durability of bond between concrete and CFRP strips installed according to EBR and NSM techniques under the effects of ageing induced by outdoor conditions for a period of three years. Specimens were placed in four different outdoor environments (E3-E6) with ageing mainly induced by freeze-thaw attacks, carbonation, airborne chlorides, and elevated temperatures. Besides, the study included a reference environment (E1: ≈20 C / 55% RH) and another environment (E2: ≈20 C / water immersion). The bond test results for the specimens collected from the aforementioned outdoor environments showed a low degradation of the CFRP-concrete bond after three years.por
