Performance-based concept for sufficient ASR resistance of concrete
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.
Stability of calcined clays during storage
New functionalities of textile-reinforced concrete through titanium dioxide modifications Subsidiary project: fine-grained concrete and 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
Crash Course on Cement Production and Use
Our training schemes introduce career starters to cement technology, taking their different engineering or scientific backgrounds into account. This course provides a one-week in-depth training session which covers all relevant aspects of the cement manufacturing process including chemistry, mineralogy and environmental aspects. Quality control and cement performance in mortar/concrete will also be addressed.
Firing Alternative Fuels 2025
This course covers all the relevant aspects concerning the use of alternative fuels in cement plants. Starting with the main political drivers such as the circular economy and the European waste fuel strategy, the training will give a detailed view of the current state-of-the-art-situation with regard to the use of alternative fuels in the EU. In this context, pre-treatment and suitable quality control of alternative fuels will be also explained and presented. A main focus will be given to the drivers and barriers of the use of alternative fuels within the burning process. Key issues will be explained and discussed with the participants. Finally, technical feasibilities, case studies and optimisation potential will be part of the training course.
Cements of the Future 2025
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.
VDZ Congress on 6 - 8 November 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 in the context of transformation of the cement industry on its way towards climate neutrality.
