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.
The project investigates the existing 1st generation oxyfuel technology and an innovative 2nd generation oxyfuel concept with the ultimate goal of reducing CO₂ avoidance cost, increasing plant efficiency and strengthening the overall competitiveness.
The aim of the CLEANKER (CLEAN clinKER) project is to perform large-scale testing of this technology as an integrated method (Technology Readiness Level 7). It is planned to treat 4 000 m³/h exhaust gas in a demonstration plant to be connected to an existing kiln line at the Buzzi Unicem works in Vernasca in Italy.
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.
As part of the research project, the German cement industry is to be provided with a utility model of a new type of apparatus for quasi-continuous incoming inspection of SRF deliveries. Based on a fast, technically robust and efficient characterisation of flight capability, humidity and optically detectable features of SRF, a system shall be developed, constructed and tested in practice.
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.
The oxyfuel technology is to be investigated qualitatively using a dynamic process simulation. This will provide a basis for the control and optimization of oxyfuel systems, resulting in a faster rollout of this crucial technology for CO₂ reduction.
The IGF project 19295 N intended to devise a testing and assessment system that better reflects the cements’ material properties.
The aim of this research project was to create basic knowledge on the results of different processing and compaction measures in correlation with the properties of the fresh concrete.
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.
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.
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”.
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.
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 material mixtures with X-ray amorphous materials (e.g. ternary cements with calcined clay and/or recycled concrete fines). In a next step, the findings on the analytical method and evaluation routines developed for cement are going to be evaluated with regard to their transferability to siliceous aggregates for estimating its alkali sensitivity.
The subject of the IGF research project 22502 N is the application of X-ray diffraction analysis for production and quality control of calcined clays and cements produced with them, in order to accelerate the development of cements with further reduced clinker content within the framework of the decarbonisation of the cement industry.
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 refractory lining in the kiln. Exact knowledge of these effects is indispensable for the further increase of the alternative fuel rate and the simultaneous optimisation of the kiln operation as well as for the maintenance of the clinker quality and the service life of the refractory lining.
The aim of the research project is to investigate the suitability of previously largely unused mineral secondary raw materials from the stone and earth industry as a resource-conserving and climate-friendly main cement constituent. The use of cal-cined clays from secondary raw materials instead of conventional main cement constituents or high-quality primary clays can make an important contribution to the production of climate-friendly and resource-efficient cements.
The aim of the research project was to develop a procedure for analysing trace elements on cements using X-ray fluorescence analysis. In addition, precision data and application limits were to be determined, which are essential in order to be able to classify the results.
The research project analysed whether sulphate-rich process dusts can be used to optimise the sulphate content of cements, thereby saving anhydrite/gypsum and, in particular, improving the early strength of cements with several main constituents. Furthermore, it was to be determined whether isothermal heat flow calorimetry can be used as a fast and cost-effective investigation method for this purpose.
In CaLby2030, the deployment of Calcium Looping technology (CaL) using Circulating Fluidised Bed reactors (CFB) in the cement industry will be investigated, aiming at efficient CO₂-Capture without compromising clinker production or product quality. A technology scale-up will be also evaluated in a German cement plant by exploring different retrofit possibilities. Besides the cement sector, the deployment of CFB-CaL technology in other relevant sectors will also be investigated.
