Concrete surface needs to be properly prepared prior to repair of concrete structure. The main objective of concrete surface treatments is to remove deteriorated concrete or any type of layer that can cause a decrease in adhesion, as well as to enlarge the area of the contact zone to achieve a mechanical interlock with repair material. Various treatments are used for concrete surface preparation. As a result, different roughness levels are obtained. The concrete surface geometry can be characterized with various methods at different level of observation.

The aim of this work is the analysis of an effect of surface treatment on concrete surface geometry using laser profilometry. Several types of concrete preparation techniques were selected to obtain different levels of the surface roughness of concrete substrate. For each type of sample the following parameters of surface geometry were determined: waviness and roughness amplitude parameters, Abbott’s curve parameters and fractal dimension. Usability of the determined parameters for characterization of surface geometry was analyzed. The obtained results were compared with parameters of surface geometry previously obtained for the same samples using microscopic method and “sand” (macroscopic) method.

This contribution has been prepared in the framework of the research project granted by Dean of Civil Engineering Faculty, Warsaw University of Technology - grant number 503 G 1084 3705.
