Results (German): Granulometry of cement main constituents – Influence on the durability of concrete made with cements containing limestone
The aim was to determine systematically the granulometric influences of the main constituents Portland cement clinker (K), limestone (LL), blastfurnace slag (S) and fly ash (V) as well as the substance-specific impacts of the particle size distributions on cement, mortar and concrete properties.

VDZ ensures efficient and practical learning by providing a wide range of vocational training courses and (online) seminars covering technical basics, special technical knowledge and education courses for managers.
Recycled clay brick containing materials as a raw material in resource efficient cements and durable concretes
The topic of the research project is the utilisation of brick-containing materials from the recycling of mineral construction waste. It is being investigated whether and how resource-efficient cements can be produced with processed brick-containing construction waste and reduced clinker content, thus reducing process-related CO₂ emissions.

The use of fines from concrete recycling plants as cement constituents is currently insufficiently investigated and requires further research. The basic prerequisite for the utilisation of the fines will be to be able to characterise the material properties as quickly and comprehensively as possible and to ensure a constant material flow. An essential part of the research project is therefore the development of a rapid test method with which the properties of these fines can be estimated, among other things, by measuring the residual reactivity.
