Abstract
Methods for the non-destructive characterization and testing of wood and reinforced concrete are presented in introductory lectures. Afterwards selected experiments such as measurement of humidity, ultrasound, hardness and porosity are performed by the students. Some parameters that influence materials properties are tested. A written report with results and discussion has to be prepared at the en
Objective
Important non-destructive test methods shall be learnt. These methods that are based on the same physical principles (e.g. resistance measurement, ultrasound, hardness) are used for wood and concrete in a comparative way. The course shall the address the fundamentals for condition assessment of structures in wood and reinforced concrete.
Content
Detailed knowledge of the microscopic structure of concrete and wood. Knowledge of non-destructive test methods for concrete and wood (humidity, ultrasound, hardness, etc.). Problems in calibration of measuring instruments, influence of disturbing parameters (e.g. temperature). Basics of condition assessment of wood and reinforced concrete structures, assessment of deterioration processes (corrosion). Writing of reports for condition assessment. Possibilities of restoration of structures.
