Distributes strains in fibre-reinforced concrete mixed with the ground
The subject of the project was to investigate the structural behaviour of a new material: fibre-reinforced concrete mixed with the ground. Its possible applications include slurry walls and other geotechnical structures. After experiences in the research field, six reinforced beams were now prepared for mechanical tests in laboratory conditions. Each beam was equipped with four EpsilonSensors and four EpsilonRebars to monitor strains and crack development.

Benefits of using the DFOS monitoring system
Results of using the DFOS monitoring system
The mechanical tests were performed at the Cracow University of Technology laboratory. Thanks to thousands of sensing points inside the element, it was possible to analyse its behaviour in a very detailed way, including detecting all the cracks in the tension zone.
Moreover, one of the goals was to analyse the quality of the results obtained by sensors with different stiffness: EpsilonSensors (negligible elastic modulus not influencing the specimen) and EpsilonRebars (high stiffness locally strengthening the specimen).
