As plans are progressing for the CCUS infrastructure for transporting, storing and using CO₂, it is becoming increasingly clear that the separated CO₂ must be very pure in order to be used or stored. CC technologies are currently being planned with considerable engineering effort and electricity consumption for gas cleaning systems to separate unwanted accompanying substances. This is where this project comes in. It aims to investigate an innovative concept that could significantly reduce this effort.

Precise material balances and up-to-date transfer factors are essential for evaluating trace element emissions in cement clinker production. Outdated data makes it difficult to use modern, CO₂-neutral raw materials and fuels. The project aims to update the transfer factors to support industry, the environment and climate protection.

In the IGF research project 23643 N, relationships between the particle size distribution of different cement compounds (clinker, calcined clays and limestone powder), and their reactivity and influences on cement performance are being systematically investigated.

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.
