New sensor-supported method for rapid and user-friendly testing of fresh concrete sedimentation stability, developed at IWB Stuttgart by Franz Ludwig GmbH, addresses challenges with modern concretes Challenges with Modern Concretes Modern concretes are becoming increasingly complex to meet current demands like slender structures and filigree components. The use of highly effective superplasticizers makes these concretes not only more performant but also more susceptible to environmental factors and segregation. Maintaining the desired fresh and hardened concrete properties is becoming increasingly problematic. To date, quick and user-friendly methods for on-site testing of concrete sedimentation stability are lacking. Therefore, it is crucial to examine these concretes for their tendency to segregate before placement. Developing a Novel Testing Method At the Institute for Construction Materials (IWB) at the University of Stuttgart, a sensor-based testing method is being developed to specifically examine soft concretes for sedimentation stability. Initial preliminary tests have already successfully confirmed the basic principle of the testing. The testing device,
