The capture of CO₂ and its subsequent use and storage are key elements of the cement industry's decarbonisation strategy. The separation of CO₂ from waste gas is an energy-intensive and complex process. This process can be made simpler and more efficient by achieving the highest possible CO₂ concentration in the flue gas. If the calcination of the raw meal is separated from the actual clinker burning process, this considerably facilitates the concentration of CO₂ in the flue gas and reduces the "contamination" of the CO₂ with (false) air.

The thesis developed a "Performance-based concept for sufficient ASR resistance of concrete" to more effectively prevent damage to concrete structures due to alkali-silica reaction (ASR). This is based on a new method for testing and evaluating the effective alkali content, especially of clinker-efficient cements with several main constitutens, and on the results of the long-term behaviour of concrete cubes in outdoor exposure site tests.

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.

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.

Clinker production is the most energy-intensive process step in cement manufacturing. It can represent up to 90 % of the total energy demand in a cement plant and is therefore a main focus not only with regard to cost optimisation and quality improvement of the final product, but also regarding emission control and the reduction of impacts on the environment. VDZ’s training will enable participants to obtain a deeper knowledge of the clinker production process and a better understanding of the impacts that daily decisions of plant personnel can make on the plant’s performance (quality, electrical energy use, fuel consumption and emissions).

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.
