High-quality recycling of crushed concrete sand
In the ZIM research project, used concrete is processed in such a way as to improve the usability of all fractions generated, in particular the crushed sand and the fine fraction. To this end, tests are also being carried out on the pozzolanic reactivation of the recycled concrete fines.

Systematic application of IR spectroscopy to strengthen the circular economy in the construction industry
In this research project, IR spectroscopy in combination with mathematical tools (chemometrics) is going to be evaluated as an analytical method for the characterisation of silica based materials, primarily X-ray amorphous materials, with regard to the reliable determination of the composition of ma ...

Contribution of calcined clay as main constituent of cement to prevent alkali-silica reaction
The current requirements for low alkali cements mean that calcined clays can hardly be used as main constituent in such cements due to their alkali content. However, it is known that pozzolanic SCMs contribute to the prevention of ASR. The aim of the research project is therefore to systematically i ...

Performance of ternary cements with Portland cement clinker, calcined clay and limestone as the main constituents
The project systematically investigates the performance and hydration behaviour of ternary cement (KQL) with clinker (K), calcined clay (Q) and limestone (L) as well as key durability aspects of concretes produced with these materials.

Process atmosphere during clay calcination – effects on emissions and product properties
Calcined clays as the main cement constituent are an essential part of the cement industry's decarbonisation strategy. Many clay deposits have iron-rich impurities that form hematite during calcination, which colors the product, the cement and ultimately the concrete red. A reducing atmosphere durin ...

Clinker burning with alternative fuels at low process temperatures - effects on coating formation and on the corrosion of refractory products in the cement rotary kiln as well as on the performance of cement
The replacement of primary fuels by alternative fuels is of great economic and ecological importance for the cement industry and is to be increased in the future. The fuel ashes are used as raw material in the cement clinker and influence its properties as well as the coating formation on the refrac ...
