Abstract

L. Courard1, F. Michel1, D. Schwall1, A. Van der Wielen1, T. Piotrowski2, A. Garbacz2, F. Perez3 & B.

The effects of surface preparation technique are rarely clearly described and parameterised: it is consequently difficult to point out the real influence of roughness on adhesion results. A large research project has been realized with regards to the influence of concrete substrate strength and preparation technique efficiency. The surface roughness of concrete has been quantified by means of the projection \“Moiré” technique, which is an interferometrical measurement method. Comparison between polished, scrabbled and hydro-jetted surfaces evaluation is presented. Keywords: concrete, surface, micro-cracking, NDT, roughness.
