The transfer and networking project ReInvent aims to provide technical and organisational support for the BMBF funding measure KlimPro-Industrie.
"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 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.
The research project was investigating the extent to which the different types of mercury bond, the alkaline atmosphere and high dust loading influence the effectiveness of possible additives such as activated charcoal, open-hearth coke or other calcium compounds and mixtures of these.
The aim of the research project was to obtain general NOₓ emission abatement to 200 mg/m³ with a minimal NH₃ slip of max. 30 mg/m³ in cement industry rotary kiln plants with precalcination.
Taking into account the experimental results and a techno-economic analysis, CEMCAP has developed a decision basis for CO₂ capture technologies in the cement industry. This should enable European cement producers to perform plant-specific CCS economic analyses and adapt to a world with limited carbon emissions. From a European perspective, CEMCAP aims to expand the portfolio of cost- and resource-efficient options for CCS and thus the possibilities for reducing greenhouse gas emissions.
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.
The aim of this research project was to investigate the issue of high-temperature corrosion in the hot area of the preheater and the rotary kiln.
The aim of the research project was to identify those fuel particles which potentially cause the greatest disturbances and to determine their rate of conversion in the flame and in the clinker bed. A further goal was to derive quality criteria for AF, to elaborate recommendations for the optimisation of fuel feeding systems and to develop a tool to estimate the suitability of an AF.
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 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 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.
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.
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 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 IGF research project 22330 N is concerned with the environmental compatibility of cement-bound building materials in special application situations in which the binder comes into contact with groundwater during the processing phase. A procedure is being developed to demonstrate the environmental compatibility of the building materials in these situations as well.
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.
