Introductory lectures will introduce methods for non-destructive characterization and testing of wood and reinforced concrete. Following these lectures, practical sessions will be conducted both in the laboratory and outdoors, offering participants the chance to engage in hands-on measurements using a variety of state-of-the-art devices.
Lernziel
The goal is to get to know and understand important non-destructive test methods for the condition assessment of materials and civil engineering structures. These methods are based on similar physical principles (e.g. resistance measurement, ultrasound, hardness) for the characterization of both wood and concrete. The course covers the fundamentals of these methods, their practical application, and the interpretation of the test results. Training of presentation and report writing skills.
