Japanese-Swiss Workshop Service Life Assessment of Concrete Structures

18 October 2018 Campus Trevano, Via Trevano Iscrizioni CH-6952 Canobbio www..ch/go/concrete Service life management of concrete structures assumes the development and application of a reliable system to assess the actual state of the concrete. The evaluation of the service life enables the improvement of the maintenance and rehabilitation plans. Common research interests have been found between SUPSI and Japanese academic (Univ. Hiroshima) and engineering (NEXCO) organizations. Finding alternative methods to make the service life assessment of structures exposed to risk of chloride- and carbonation-induced corrosion, simpler, more comprehensive and less costly is a common concern. Japan and are at the forefront of applying non-destructive (sometimes combined with destructive) tests to assess, on site, the resistance of the cover concrete (‘covercrete’ in short) to the penetration of aggressive species (chiefly CO₂, Cl⁻). The objective of this Workshop is to cross-breed the experiences gathered in both countries and disseminate the results of these experiences among the interested professionals coming from both academic and practitioners’ worlds.
