Ziel des Forschungsvorhabens war es, den Einfluss von Nebenoxiden aus Brennstoffaschen auf die Bildungstemperaturen der Klinkerschmelze und auf die damit verbundene Klinkermineralogie herauszuarbeiten. Ebenso sollten die Auswirkungen der verringerten Prozesstemperatur und der veränderten Eigenschaften der Klinkerschmelze auf die notwendige Bildung von Coatingschichten sowie die Feuerfestkorrosion und damit auf die Haltbarkeit der feuerfesten Zustellung in der Sinterzone des Drehrohrofens aufgeklärt werden.

Ziel des IGF-Vorhabens 19276 N war es, grundlegende Erkenntnisse zur bedarfsgerechten Verdichtung von leicht zu verarbeitenden Betonen in Abhängigkeit der Frischbetoneigenschaften zu gewinnen. Die Untersuchungen sollten dabei den gesamten möglichen Bereich der Frischbetoneigenschaften von LVB abdecken.

Redol deals with closing material cycles using the city of Zaragoza as an example. The research project focuses on solid urban waste, which is an abundant source to produce circular products. Five value chains for solid urban waste in the Aragon region will be redesigned in order to be able to produce circular products using an industrial-urban symbiosis approach.

The aim of IGF project 21619 is to develop a training simulator with which learners can independently solve typical process engineering tasks within a virtual reality (VR) environment, particularly in connection with ball mills.

The aim of the research project is to investigate the suitability of previously largely unused mineral secondary raw materials from the stone and earth industry as a resource-conserving and climate-friendly main cement constituent. The use of cal-cined clays from secondary raw materials instead of conventional main cement constituents or high-quality primary clays can make an important contribution to the production of climate-friendly and resource-efficient cements.

Participants will get a comprehensive overview of concepts for ensuring the durability of concrete structures. In addition to the damage mechanisms the concrete technology and design elements as well as the execution are explained. On the basis of examples the influence of the cement on durability-relevant parameters is going to be explained. Performance concepts and the principles of service life design are also addressed. For the participants it is possible to discuss their current issues from operational practice.

This training will provide knowledge of how to conduct and evaluate cement kiln and mill trials. Kiln and mill examinations are carried out in order to gather data on the performance and to validate warranty performance data such as the output, the energy consumption, input/output ratio or the efficiency. They also provide a reliable foundation for the optimisation of individual operational system components, the cement quality, the reduction of emissions levels and for assessment of material cycles and coating formations.

The SIMULEX® cement plant simulator for training plant supervisors, foremen, production personnel, control room operators and young engineers was developed by KHD Humboldt Wedag AG in cooperation with VDZ. For over ten years VDZ has been using the simulator within the framework of training courses and has been continually supporting the further development of the system with practical input from the industry. As a result, the simulator provides a realistic reconstruction of a cement plant with a state-of-the-art supervisory control and data acquisition system (SCADA).

Climate protection and digitisation are key challenges for the cement industry: More than 600 representatives from the international cement industry and associated suppliers, as well as from scientific and research institutes around the world, gathered at the International VDZ Congress 2018 in Duesseldorf at the end of September. Steeped in tradition, the VDZ Congress is one of the world's most important events in the industry. The 40 talks held at this year's congress focused on particularly pressing topics such as climate protection and digitisation. The participants also discussed current technical challenges and the general situation with regard to cement production. A further highlight was an evening ceremony at which the winners of the VDZ Industrial Safety Prize 2017 received their awards.
