Research projects

It was determined how the rheological properties and the consistency of fresh concrete can be improved by the adjustment of the type and proportion of fly ash or calcined clay in the cement to the clinker as well as the type and dosage of the superplasticizer.

The research project initially involved a sequence of steps to formulate robust, automated preparation methods and evaluation files and determine their reproducibility.

The aim of the research project was to determine interactions between superplasticizers and cements with calcined clay.

The main scope of this research project was to supply evidence that selected inorganic substances are suitable for the use as minor constituents.

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.

Interactions between different structured or modified methyl hydroxyethyl celluloses and cements blended with limestone, blastfurnace slag or fly ash were determined.

Various cement-chemical optimisation possibilities for cements containing fly ash with different types of hard coal fly ash were intensively investigated. Furthermore, the effects of different clinkers and sulphate carriers as well as mineral additives on hydration and strength development were determined.

The aim of the project was to address open questions of the finished project IGF 17829 N and to develop a method for determining the grading curve of aggregates in hardened concrete.
