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.

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.

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.

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.

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.

This seminar will give you a practical overview of the fundamentals of cement chemistry and the main product properties. You will learn about the origin, composition and properties of the raw materials used in the production of Portland cement clinker and cement, and understand the chemical reactions that take place during the clinker burning process. We will show you how clinker is characterised and what factors influence its properties. The hydration reactions of Portland cements and cements with other main constituents will also be covered. You will learn methods for cement characterisation and production control during the seminar.

In this advanced seminar, you will look at the current challenges facing cement chemistry in terms of resource efficiency and climate neutrality. The focus will be on the use of alternative raw materials and fuels in clinker production. You will learn about the origin, composition and properties of these materials and understand their influence on the clinker burning process. You will also be introduced to modern methods of clinker analysis to assess the effect of alternative raw materials and fuels on cement properties. Finally, you will discuss the hydration behaviour of complex composite cements and quality assurance methods in a practical way.

The 9ᵗʰ International VDZ Congress took 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 discuss the latest developments concerning the transformation of the industry on its way towards climate neutrality.
