Forschungsergebnisse: Dauerhaftigkeit von Beton nach dem Performance-Prinzip - Zustandserfassung (Projekt 1: Objektsammlung)
Ziel des IGF-Projekts war die Erfassung der Zuverlässigkeit eines repräsentativen Bauwerksbestandes, geplant und erbaut auf Grundlage der DIN 1045:2001. Hierfür sollte ein repräsentativer Bauwerksbestand ausgewählt werden, der Einwirkungen der Expositionsklassen Karbonatisierung (XC4), Chlorideinwirkung (XD3) und Frosteinwirkung (XF3 und XF4) ausgesetzt ist.
Partial oxyfuel - Separate calcination of raw meal to concentrate CO₂ in the exhaust gas
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.
Research projects
Influence of the reduction of melting point and viscosity of the clinker melt by ashes of alternative fuels on sintering reactions and coating formation
A database was compiled which cement manufacturers can use to influence and further optimise the formation of the melt phase by selecting suitable alternative fuels and their proportion.
Optimal compaction of concretes with high workability and high robustness
The aim of this research project was to create basic knowledge on the results of different processing and compaction measures in correlation with the properties of the fresh concrete.
ECo – Efficient Co-Electrolyser for Efficient Renewable Energy Storage
The aim of ECo project was to utilise CO₂ for co-electrolysis SOEC in combination with electricity production from renewable sources for storage as methane presented an interesting approach to handling CO₂ emissions from the cement industry in a future sustainable energy system.
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.
Burning Technology in Cement Production
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).
Events
VDZ Congress 2024
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.
