Procedures for E II aggregates

VDZ and the Brandenburg Technical University Cottbus-Senftenberg (BTU) investigated whether it is possible to define an alkali sensitivity class E II-S on the basis of the 40 °C concrete test with cloud chamber storage. In addition, criteria for the rapid test procedure and the 60 °C concrete test as well as the BTU-SP rapid test were also derived.

Determination of characteristic values based on the degree of hydration for predicting the durability of concrete

Mortar and concrete trials were used to determine characteristic parameters, such as the void filling of the cements, their hydration characteristics, the porosity of the mortars and concretes made with these cements, and the durability of the concretes.

Boundary conditions for accurately achieving projected concrete properties in the modern 5-material system of diverse concrete constituents

Within the framework of the research project, the intention was to identify the most important influence parameters that are responsible for showing unscheduled properties such as changed consistency, signs of sedimentation, or an accelerated or decelerated strength development in certain cases of fresh concretes which are produced over prolonged periods.

Optimisation of concrete compositions based on their serviceability limit state: A step towards a further reduction of CO₂ emissions of concrete production

The target of this research project was to develop a comprehensive database regarding the material parameters carbonation and chloride resistance for different cement types and concrete compositions. The investigations focused on concrete compositions that contain cements with low clinker/cement factors.

Transferability of results from laboratory test procedures to determine the frost de-icer resistance of pre-fabricated paving products in practical conditions

This aim of this research project was to create a secured assessment background for testing the frost de-icer resistance of earth-moist produced concrete paving stones. The proposals could possibly be developed for testing in realistic conditions.
