Radiographie im Bauwesen – Einsatzmöglichkeiten in der Praxis im Rahmen der ZfPBau

Radiography in civil engineering – practical applications of RT in NDT-CE. Radiographic Testing (RT) has been a proven testing method in NDT for decades. This is because RT is the only method providing direct imaging of the inner structure of welds, castings, and workpieces. However, radiography is widely unknown in the field of non-destructive testing in civil engineering (NDT-CE) in Germany – although great progress has been made in the last decades, especially in the field of digital imaging and mobile applications. This allows for many practical testing tasks, e. g. on-site quality assurance, damage assessment, and non-invasive investigation of buildings under a preservation order. In general, RT allows for identification, size and depth determination of reinforcement, tendon ducts and other components. Investigation and evaluation of cracks and corroding steel should be possible as well and may be the aim of future research work. This paper outlines basics, possibilities and limitations of radiography in civil engineering and shows its potential basing on practical applications. © 2022, Ernst und Sohn. All rights reserved.
