Abstract (en)
The method is conceived for superficially treating granite slabs or pieces, being based on a laser beam irradiation for obtaining a rough or bushhammered surface of the granite slab. The method is flexible in its application, permitting obtaining different types of surfacings on the same granite piece without needing to change the equipment or tool, it only being necessary to modify the processing parameters. The method involves a significant improvement compared to the traditional methods, such as the mechanical bushhammering, considerably reducing the noise produced by the process and the treatment or bushhammering of thinner granite slabs being possible. The granite slabs treated by means of the method can be used in both sidings of buildings and in pavements, and as a decorative piece in general.
