Performance-based concept for sufficient ASR resistance of concrete

Available in German and German

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.

Research projects


Completed

New functionalities of textile-reinforced concrete through titanium dioxide modifications Subsidiary project: fine-grained concrete and cement-bound adhesive

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.

Completed

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.

Completed

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

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.

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).

Seminars

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.

Crash Course Process Control

The SIMULEX® cement plant simulator for training plant supervisors, foremen, production personnel, control room operators and young engineers was developed by KHD Humboldt Wedag AG in cooperation with VDZ. For over ten years VDZ has been using the simulator within the framework of training courses and has been continually supporting the further development of the system with practical input from the industry. As a result, the simulator provides a realistic reconstruction of a cement plant with a state-of-the-art supervisory control and data acquisition system (SCADA).
