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.
Testing and assessment of effective alkali content in cements
Optimal compaction of concretes with high workability and high robustness
Behaviour of different aggregates under accelerating conditions in ASR testing methods
The research project should generate essential knowledge on the behaviour of different aggregates under accelerated conditions within ASR testing methods. The target was to obtain with different testing methods a consistent assessment of the alkali sensitivity of aggregates and concretes respectively and to clearly identify expansive reactions that are not caused by ASR.
DURAFOR - Forecast of durability properties of concrete with new clinker based cements
In a CORNET (Collective Research Networking) research project, the project partners CRIC (Belgium), Smart minerals (Austria) and VDZ (Germany) had combined under the consortium leadership of the VDZ to determine characteristic variables for cement and mortar samples and correlate them with the results of concrete durability tests.
CARBON CONCRETE COMPOSITE – C³-Environment: Characterisation and leaching tests for the determination of the environmental safety of C³
Goal of the research project was to generate a broad, scientific verified data base via corresponding leaching and shower tests (laboratory and outdoor tests) on carbon-concrete test specimen with different concrete covering of the carbon-fibres as well as with different percentages of the carbon-fibres to evaluate the environmental compatibility of the new, innovative composite building material “carbon-concrete”.
CARBON CONCRETE COMPOSITE – C³: Acceleration of standardisation and approval procedures in the context of test-based design and performance testing for C³ products (CarbonSpeed)
The aim of the C³ CarbonSpeed project was to create a guideline to complement the existing verification procedures of the building authorities (approval in individual cases, national technical approval) with a view to shortening the time required for the introduction of solutions with carbon concrete.
Chemistry and mineralogy
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.
