The transfer and networking project ReInvent aims to provide technical and organisational support for the BMBF funding measure KlimPro-Industrie.
The aim of IGF project 21619 is to develop a training simulator with which learners can independently solve typical process engineering tasks within a virtual reality (VR) environment, particularly in connection with ball mills.
"BetonQuali - information and qualification platform", a joint project of VDZ gGmbH and its project partners, aimed to develop and test a training method for semi-skilled and unskilled employees in the concrete industry.
In the research project, infrared cameras are used to record the surface temperature of the clinker bed in the clinker cooler. Together with calculated enthalpy flows, this allows control room personnel to identify the operating condition of the cooler. This is used in operational tests to optimise the heat transfer in the clinker cooler by controlling the drive system and adjusting the cooling air distribution.
Separate ultra-fine grinding of cement - Energy-efficient grinding meets optimised cement and concrete properties. Today, future-oriented cements can already be produced more sustainably and efficiently by using various components of different finenesses.
Elemental white phosphorus (P4) is indispensable for key industries such as in the food and pharmaceutical sectors and is therefore a strategic raw material of high relevance. In the FlashPhos project, the sustainable production of white phosphorus using sewage sludge will be demonstrated on a large scale.
ACCSESS takes a cross-sectorial approach to CO₂ Capture, Transportation, Utilisation and Storage (CCUS), working with Pulp and Paper, Cement, Waste to Energy, and Biorefining, all industries with big potential for carbon dioxide removal.
The aim of the IGF project 21791 N is to better understand the influence of ceramic grinding media (balls) on the comminution process and the product quality during cement grinding in ball mills. The data will serve as a basis for designing and predicting the energy requirements and behaviour of grinding plants when using ceramic grinding media.
The main objective of the research project is to investigate both technically and economically the application of hydrogen in the calciner in the cement production process for the first time.
Redol deals with closing material cycles using the city of Zaragoza as an example. The research project focuses on solid urban waste, which is an abundant source to produce circular products. Five value chains for solid urban waste in the Aragon region will be redesigned in order to be able to produce circular products using an industrial-urban symbiosis approach.
EN 197-5 defined the clinker-efficient cements CEM II/C and CEM VI. Technical approvals for the application of CEM II/C cements have been issued. For a widespread application, it is important that all parties involved develop confidence in the new products. With new findings on fresh concrete properties, hardening behaviour and durability two research projects of the VDZ Concrete Technology Department will provide an important basis for application of these cements in concrete for the construction industry.

In this project, the systematic classification of the carbonation and chloride penetration resistance of concretes will be investigated. Based on these results, recommendations for action will be derived for production and conformity control within the framework of a performance-based durability concept.

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 aim of the AiF research project was to identify the causes of the sometimes greater scatter rates in the analysis results in the case of comparison trials for the long-term tank test.
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 main scope of this research project was to supply evidence that selected inorganic substances are suitable for the use as minor constituents.
The aim of the research project was to determine interactions between superplasticizers and cements with calcined clay.
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.
Interactions between different structured or modified methyl hydroxyethyl celluloses and cements blended with limestone, blastfurnace slag or fly ash were determined.
