Influence of the surface properties of concrete on the adhesion of coating: Characterization of the interface by peel test and FT-IR spectroscopy

► Several parameters influence adhesion between concrete and protective coating. ► A reproducible methodology of peel tests is developed to measure fracture energy. ► A flexible porous membrane is introduced into the liquid coating before crosslinking. ► Adhesion is correlated to the composition of the fracture loci after debonding. ► The mechanical anchorage determines the adhesion level between coating and concrete.
