Abstract (en)
The concrete specimen (9), which compression strength tests have to later be performed on, and which, for reasons of manufacturing, has on one of its bases (10) an irregular surface, is arranged on a support plate (8) rotatory via a motor (6), and receives through said surface (10) the action of an abrasive disk mounted on a second support plate (14), actuated simultaneously in rotatory direction by the corresponding motor (12), so that said abrasive disk acts on the surface (10) of the specimen causing the wear thereof until achieving a perfect polish. The system comes to replace the classic capping system using the sulphur mortar method, recommended by standard UNE-EN 12390-3, consequently eliminating the contaminating effects of this capping method and permitting a surface finish to be achieved for the specimen with greater safety, greater quality and less costs.
