Innovative non-destructive inspection system for detecting structural anomalies and inner defects of raw material blocks

The project intends developing an innovative inspection system for detecting structural anomalies and inner defects in raw material blocks (marble, granite, limestone) before being cut into slabs. Today, the methods employed by stone manufacturers for assessing the quality of marble or granite blocks and slabs are based mainly on human observation, the workers' practical knowledge and experience. The development of an inspection system, based on ultrasonic detection, will enable to accurately determine stone quality in a non-destructive way. Ultrasonic systems allow to detect not only the presence of defects but also to produce accurate on-line images related to the material characterisation of the inner structure. Various ultrasonic methods have been tested by the project partners (AIDICO and ISE) and the method that has given most successful results, and which is currently being used on the developed prototype, is the MIHM (Multichannel Impact Hammer Method).
