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.
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.
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.
The IGF project 22022 N aims to evaluate the performance of high-speed sieving machines to increase energy efficiency in cement grinding circuits through optimised cement classification. The central elements here are the energy and qualitative product comparison of sieving and classifying.
The aim of the project is to investigate Machine Learning models for the characterisation of alternative fuels in the cement production. For this purpose, a public-accessible database (with fuel characteristics and images) is set-up and different machine learning models will be trained on that data, the algorithms will be tested on their robustness and suggestions for the classification of the fuel quality and its visualisation in the control room will be made.
The working plan of the Research Institute of the Cement Industry was aimed at systematic investigation of the mix formulation and workability of a nano-based cement-bound adhesive.
In the IGF (Cooperative Industrial Research) project the framework conditions for a possible performance test method for evaluating the alkali reactivity of concrete was calibrated on the basis of the requirements of the German regulations.
The aim of this research project was the laboratory and industrial production and testing of cements that contain levels of limestone above the maximum content described in DIN EN 197-1.
VDZ and the Brandenburg Technical University Cottbus-Senftenberg (BTU) investigated whether it is possible to define an alkali sensitivity class E II-S on the basis of the 40 °C concrete test with cloud chamber storage. In addition, criteria for the rapid test procedure and the 60 °C concrete test as well as the BTU-SP rapid test were also derived.
Mortar and concrete trials were used to determine characteristic parameters, such as the void filling of the cements, their hydration characteristics, the porosity of the mortars and concretes made with these cements, and the durability of the concretes.
Within the framework of the research project, the intention was to identify the most important influence parameters that are responsible for showing unscheduled properties such as changed consistency, signs of sedimentation, or an accelerated or decelerated strength development in certain cases of fresh concretes which are produced over prolonged periods.
The research project has two objectives. The first is to investigate whether certain chemical / mineralogical properties can make clinker more robust against pre-hydration effects. Secondly, it will be investigated which measures can be taken to counteract possible negative effects, in particular by adjusting the sulphate carrier composition.
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 during calcination and/or cooling can prevent the formation of hematite. Systematic findings on the influence of secondary constituents in clays on their reactivity, emissions and cement-technical properties have hardly been available to date and are to be systematically investigated in the project.
The aim of the research project was to investigate the suitability of largely unutilised mineral secondary raw materials from the stone and earth industry as a resource-conserving and climate-friendly main cement constituent. The utilisation of calcined clays from secondary raw materials instead of conventional cement main constituents or high-quality primary clays can make an important contribution to the production of climate-friendly and resource-efficient cements. This means that the transformation process of the cement industry can be shaped in a way that is not only cli-mate-friendly but also resource-efficient.
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.
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.
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.
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.
