Stone decay is affected by the influence of climatic factors. In particular marbledegradation, that could be expressed by decohesion and /or bowing, is mainly due to the action oftemperature and water (rains and relative humidity). In this work non destructive and destructive testshave been performed to evaluate the decay of marble slabs subjected both to natural exposition and toartificial ageing tests (Lab - Bow test). Measurements of Ultrasonic Pulse Velocities (UPV) andbowing have been executed periodically on marble slabs exposed for a period of four years aspreliminary field tests. On the base of this work an integrated test methodology to monitoring andpreviewing the behaviour of façade slabs have been set up. The methodology has been applied on themarble façade of modern building of centre Italy and consists of in situ and laboratory tests. Inlaboratory a destructive test (flexural strength) has been added to the non destructive tests to evaluatethe decay before and after cycles of an ageing test. The results of the analysis, show an evaluative trendof the decay, though it changes its slope after 25 cycles of the ageing test. Moreover this workconfirms the effectiveness of the employed non destructive tests and their god correlation with themechanical tests. |
