Advanced characterization of adhesively bonded CFRP-to-concrete systems

In the context of strengthening existing structures, the use of fibre-reinforced polymer materials has been continuously increasing as an alternative to traditional materials, due to their superior durability (absence of corrosion), lightweight, low maintenance cost, and rapid installation. Adhesive bonding techniques for strengthening existing structures, such as near-surface mounted (NSM) and externally bonded reinforcement (EBR) are usually preferable. Despite the increasing knowledge, the long-term performance of these strengthening techniques under hygrothermal ageing conditions is still not clearly understood, limiting their use. This work aims to give new insights for reliable predictions of the long-term performance of these strengthening techniques, supported by advanced and innovative numerical modelling, properly calibrated with a refined experimental program that will be developed in this work. These outcomes will provide new knowledge on the most influencing parameters, serving as a basis for the development of simplified design recommendations.
