Influence of surface concrete preparation on adhesion properties of repair materials

The research programme was designed to present the performance of repair on horizontal surfaces through trial works on models, such as for example on bridge concrete slabs whose deteriorated surface layer needs to be removed and the pavement slab reshaped by applying the repair system procedure. The aim of the investigation was to determine optimal technology for the concrete surface preparation and the type of repair material which meets the new adhesion criteria (fa ≥ 2.0 N/mm2). Pull- off testing, roughness measurement and microscope analysis were used for evaluation of applied repair systems.
