Repairing of Damaged Stone in Monuments and Stone Buildings

Abstract:

The main causes of rock degradation in stone buildings are discussed and the current methods of recovering damaged stones are summarized. The Alkaline Activation seems to present a great potential to deal with particular cases of damaged stones resulting mainly from fracture incidents provoked by physical actions, where the global substitution of the stone itself is not considered. A practical case of recovering granite on the windows frames of a beautiful chalet to be intended for the Municipal Archives at Vila Real is described, in what is considered to be the first experiment of this technique in recovering building stone.
