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,

New measuring system from Franz Ludwig GmbH optimizes concrete quality control directly in the truck mixer drum to increase precision and efficiency on the construction site. The quality of concrete is crucial for construction projects. Franz Ludwig GmbH, with almost half a century of experience in moisture measurement of bulk materials, has developed an innovative measuring system for truck mixer drums: the FL-Mobimic-Inspector. This system aims to precisely monitor concrete quality and thus minimize fluctuations, for example in water content, which can significantly affect concrete properties. It generates process-relevant data directly in the drum of the concrete truck mixer to ensure the high performance of concrete produced in precast or ready-mix concrete plants. Comprehensive Data for Optimal Concrete Consistency The FL-Mobimic-Inspector collects a variety of parameters relevant to concrete quality, including water content (optionally as w/c ratio or in l/m³), consistency, slump, temperature, drum rotation direction and speed, drum filling level, and even the amount of wash water in an empty mixing drum. Central positioning of

Modern digital measurement techniques from Ludwig Moisture Control enable precise and rapid moisture determination in bulk materials. Mobile, battery-powered devices deliver reliable results and optimize processes Precise Moisture Measurement as a Key to Quality The determination of moisture content in bulk materials and their raw ingredients is a critical factor for product quality and processability. Especially in highly automated modern process plants, the rapid and precise acquisition of moisture values is becoming increasingly important. Conventional measurement methods are often time-consuming and can yield inaccurate results with small sample sizes. Digital inspection techniques offer significant advantages: they provide accurate measurements within seconds and efficiently capture data for further processing. Mobile Technology for Practical Applications To meet the demands of practical use, Ludwig Moisture Control has developed a modern, mobile measuring device. The measuring probes are battery-powered and wireless, allowing for high flexibility in application. All measurement signals are digitally processed directly in the probe and sent via radio to end devices such

The new FL Mikro T2 water dosing device from Franz Ludwig GmbH optimizes moisture measurement and water dosing for more precise concrete production with low investment costs. Improved Production through Moisture Measurement In modern mixing plants, precise measurement, calculation, and dosing of water are crucial. This requires comprehensive know-how regarding production processes and technology. The FL Mikro T2 enables more accurate and consistent concrete production with manageable investment costs, especially when the mixing plant control system lacks specific expertise in measurement and control technology. Precise and repeatable consistency control remains the most important feature for effective concrete processing and is considered critical in the mixing process. Easy Integration and Robust Technology The replacement of existing systems with the FL Mikro T2 could be carried out within a few hours, without mechanical adjustments or changes to the communication with the control system. Commissioning, calibration, and personnel training were successfully completed during ongoing operations. The device was deliberately developed
