A laboratory method and a method on the internal particle size distribution that can be used on-site in a cement plant were developed in this research project.
The aim of the project was to investigate the suitability of the Ono method for evaluation of burning conditions even on clinker burnt with alternative fuels. Furthermore the focus of the project was the development of a methodology for correlations between microscopically and mineralogically analysed clinker properties and burning conditions.
The aim of this research project was to determine interactions between superplasticizers and cements in the temperature range of 5 °C (41 °F) to 30 °C (86 °F). The main focus was on superplasticizers based on polycarboxylate ether and cements with several main constituents.
The research project initially involved a sequence of steps to formulate robust, automated preparation methods and evaluation files and determine their reproducibility.
The new research project focussed on the optimisation of pozzolanic cements concerning the processing and composition of their constituents as well as the durability of concretes made of these cements.
The SVA test method should be modified in a way that it is possible to achieve clear test results for standard cements with known high or low sulfate resistance.
Interactions between different structured or modified methyl hydroxyethyl celluloses and cements blended with limestone, blastfurnace slag or fly ash were determined.
As part of the project, methods were developed that allow the cement content, cement type and additive content in hardened concrete to be reliably determined.
