Abstract
Much of heritage buildings are made of stone, mortar or brick, and degradation processes are inevitable. Due to historical and cultural value, non-destructive evaluation techniques (NDE) are essential for the assessment and restoration tasks.
In this work, we study the capability of ultrasonic to detect fissures and to determine the degree of consolidation in high resistance mortar, similar to historical stone materials. To join this aim, artificial and controlled cracks/fissures have been generated and have been consolidated simulating different types of failures, filling or no adherence. The probes have been analysed by means flexion and compression strength testing, destructive testing. During the process, the probes have been measured by ultrasounds and the results have been correlated with destructive testing results. Their sensibilities have been analysed and justified. It is concluded that certain ultrasonic parameters offers a viable alternative to ED to detect cracks and to evaluate the degree of consolidation.
