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
The aim of this research project was the laboratory and industrial production and testing of cements that contain levels of limestone above the maximum content described in DIN EN 197-1.
Process Technology of Cement Production (In-Class Training)
This In-Class Training consists of two modules: "Grinding Technology and Raw Material Preparation" (Module 1) as well as "Clinker Production and Material Technology" (Module 2). Each module has a duration of one week. The course gives a deep insight into cement production technology, covering topics from quarry operation to cement grinding.
VDZ e-Learning Platform: Online Courses on Cement Production and Concrete Construction Methods
With us, you can expand your knowledge around the production of cement and lime, as well as in the area of concrete technology. As a competent partner, we have been offering our customers individual qualification solutions since 2010. In addition to German-language online courses, we also offer English- and Russian-language courses and other services.
Firing Alternative Fuels: Opportunities, impacts on process, optimisation and limitations (Training course 2)
VDZ offers an online course that 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. Relevant aspects will be explained and discussed with the participants. Finally, technical feasibilities, case studies and possible optimisation potential will be part of the training course. This training course provides four half-day training sessions in a webinar format. This unique format enables the employees to combine an adequate learning pace with their daily work in the plant.
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.
