RT Journal Article T1 Non-destructive testing for the assessment of granite decay in heritage structures compared to quarry stone A1 Fort González, Rafael A1 Álvarez de Buergo, Mónica A1 Pérez-Monserrat, Elena Mercedes AB Several types of granite found in two architectural heritage monuments were assessed with two non-destructive, portable techniques: Schmidt hammer rebound and ultrasound velocity (Vp). Similar assessments were conducted on the rock from which the granite was originally quarried for comparison. The results obtained, which revealed the existence of a direct correlation, constitute a useful indication of decay, particularly if the approximate dates of construction are known. And conversely, if they are not, such stone assessments may provide a rough estimate of when the structure was built. Both of these convenient, portable and non-destructive techniques may be used as reliable indicators of the degree of stone decay.
