Magnetometric Course (MG) + Sclerometric Course (SC) + Ultrasonic Course (UT)

Course objectives

The course includes the study of individual methodologies, case study analysis, practical exercises with subsequent data processing in preparation for the RINA Level 2 exam.

The assessment of concrete properties is of fundamental importance in the seismic verification of existing reinforced concrete buildings in accordance with the latest regulations. It can be carried out using destructive and non-destructive methods.

Part of the course will cover the SonReb method, combining the sclerometric and ultrasonic methods, allowing the limitations and margins of uncertainty inherent in each test method considered individually to be compensated for.
