Forschungsergebnisse: Einfluss der Verringerung von Schmelzpunkt und Viskosität der Klinkerschmelze durch Aschen alternativer Brennstoffe auf Sinterreaktionen und Coatingbildung
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.
Forschungsergebnisse: Optimale Verdichtung leichtverarbeitbarer Betone mit hoher Robustheit
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.
New functionalities of textile-reinforced concrete through titanium dioxide modifications Subsidiary project: fine-grained concrete and cement-bound adhesive
ASR performance testing: extending the database to include the 60 °C concrete test with particular reference to cements with several main constituents
In the IGF (Cooperative Industrial Research) project the framework conditions for a possible performance test method for evaluating the alkali reactivity of concrete was calibrated on the basis of the requirements of the German regulations.
Reducing the environmental impact of concrete construction through new types of cement and the concrete produced from them using starting materials that are available in adequate quantities
Crash Course on Cement Production and Use 2025
Our training schemes introduce career starters to cement technology, taking their different engineering or scientific backgrounds into account. This course provides a one-week in-depth training session which covers all relevant aspects of the cement manufacturing process including chemistry, mineralogy and environmental aspects. Quality control and cement performance in mortar/concrete will also be addressed.
Durability of concrete
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.
Firing Alternative Fuels
This course covers all the relevant aspects concerning the use of alternative fuels in cement plants. Starting with the main political drivers such as the circular economy and the European waste fuel strategy, the training will give a detailed view of the current state-of-the-art-situation with regard to the use of alternative fuels in the EU. In this context, pre-treatment and suitable quality control of alternative fuels will be also explained and presented. A main focus will be given to the drivers and barriers of the use of alternative fuels within the burning process. Key issues will be explained and discussed with the participants. Finally, technical feasibilities, case studies and optimisation potential will be part of the training course.
International VDZ Congress 2018
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.
