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.

Research projects
New functionalities of textile-reinforced concrete through titanium dioxide modifications Subsidiary project: fine-grained concrete and cement-bound adhesive
The working plan of the Research Institute of the Cement Industry was aimed at systematic investigation of the mix formulation and workability of a nano-based 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.
Training
VDZ E-learning
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.
Grinding Technology in Cement Production
Raw material preparation and cement grinding are the first and the last major process steps during cement production. The energy demand of these two processes amounts to up to 70 % of the electrical energy used in a cement plant. This training will enable participants to obtain a better understanding of the comminution processes as well as the equipment used for material grinding to ensure high levels of availability. This altogether will allow an optimisation of production rates and reducing energy consumption.
Cements of the Future
With the decarbonisation of cement production and the expected reduction in blastfurnace slag and fly ash quantities, unburned limestone, calcined clays, and recycled fines will gain in importance as cement main constituents. The focus will be on new, clinker-effcient cement types such as CEM II/C and CEM VI cements, whose performance allows a wide range of applications in practice. This online seminar provides an overview of the current state of development and standardisation of new cements. The possibilities and limits for practical implementation will be presented.
Events
VDZ Congress 2024 - Registration is now open
The 9th International VDZ Congress will take place in Düsseldorf on 6 – 8 November 2024. The VDZ Congress is the international scientific forum for the cement industry and its suppliers. Delegates from all over the world will come together to discuss the latest developments and challenges concerning the transformation of the cement industry on its way towards climate neutrality.
