Increasing energy efficiency in the cement industry through training by means of virtual reality (VR)
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
"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.
Process engineering investigation of the energetic-material utilisation of wastes containing carbon fibres in cement plants - EVCAZ
In the AiF project EVCAZ, the energetic and material utilisation of wastes containing carbon fibres is to be demonstrated on an industrial scale in a cement plant. The central tasks are the evaluation of the conversion success of the CF fibres, the recording of the resulting emissions and the consideration of influences on the process and the clinker quality. The findings obtained are summarised to assess health and environmental risks and to answer questions relevant to approval as a decision-making aid for cement plant operators.
Development of a method to improve clinker cooling and to increase energy efficiency in cement rotary kilns by using infrared cameras
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.
Optimisation of clinker-efficient cements by means of multimodal particle size distributions using energy-efficient products from separate ultra-fine grinding
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.
FlashPhos: The complete thermochemical recycling of sewage sludge
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 – Providing access to cost-efficient, replicable, safe and flexible CCUS
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.
Optimisation of energy demand and product quality during grinding in the cement industry through the use of ceramic grinding media
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.
REDOL - Aragon's REgional Hub for circularity: Demonstration Of Local industrial-urban symbiosis initiatives
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.
Fresh concrete properties and hardening behaviour of concretes with clinker-efficient cements CEM II/C and CEM VI
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.

Durability of concrete according to the performance principle - classification of material resistance, production control (PC), conformity criteria and control (CC)
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.
Reduction of green house gases by process innovations in the primary Industry, SP 6: Development of a methodology for cross-project and ecological potential assessment, cement industry
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.

Analysis concept for the determination of trace elements in the eluate of cement-bound building materials (IGF No. 16989 N)
Interactions between siliceous fly ash or calcined clay as cement main constituent and superplasticizers based on polycarboxylate ether as well as their influences on rheological properties of fresh cement paste and fresh concrete
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.
