"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 transfer and networking project ReInvent aims to provide technical and organisational support for the BMBF funding measure KlimPro-Industrie.
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 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.
The aim of the AiF research project was to identify the causes of the sometimes greater scatter rates in the analysis results in the case of comparison trials for the long-term tank test.
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.
The main scope of this research project was to supply evidence that selected inorganic substances are suitable for the use as minor constituents.
The aim of the research project was to determine interactions between superplasticizers and cements with calcined clay.
As part of the project, methods were developed that allow the cement content, cement type and additive content in hardened concrete to be reliably determined.
Interactions between different structured or modified methyl hydroxyethyl celluloses and cements blended with limestone, blastfurnace slag or fly ash were determined.
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.
