Abstract(s) :

(Anglais) A challenge in the restoration of historical buildings is the correct identification of materials which need to be strengthened in order to guarantee their durability and the evaluation of the results of consolidation treatments which may be applied during their repair. Methods which make such a complex characterization possible are rare. This paper presents an investigation carried out at the University of Mons (Belgium) in collaboration with the Technical Support and Control Unit, Restoration Directorate, of the Walloon Region, aiming to evaluate the effectiveness of consolidants used to strengthen stone masonry. The characterization of the materials is based on a novel semi-destructive scratching method which allows tomographic representation of the strength of the damaged and treated areas. This paper describes the experimental methodology and presents results from laboratory experiments as well as a case study.
