"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 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.
Precise material balances and up-to-date transfer factors are essential for evaluating trace element emissions in cement clinker production. Outdated data makes it difficult to use modern, CO₂-neutral raw materials and fuels. The project aims to update the transfer factors to support industry, the environment and climate protection.
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 subject of the research project is the fine-tuning of dry cement raw materials. The focus is on the influence on the electrical energy requirement during the comminution of the raw material and the thermal effects on the subsequent clinker burning process, caused by a changed raw meal granulometry.
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.
SCI4climate.NRW analyses technological, ecological and economical challenges of an institutional and infrastructural transformation of manufacturing companies in energy-intensive primary industries in North Rhine-Westphalia towards a sustainable climate-neutral industry by 2050.
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.
Aim of the project was to improve the early strength performance of blastfurnace cements by a systematic adjustment of the clinker phase composition and/or addition of mineralisers in the clinker production process.
The objective of the research project was to determine the reliability of reinforced concrete structures, planned and built according to DIN 1045:2001, ZTV-ING and ZTV-W. The structures selected were exposed to carbonation (XC), chlorides (XD) and freeze-thaw (XF).
The main scope of this research project was to supply evidence that selected inorganic substances are suitable for the use as minor constituents.
The new research project focussed on the optimisation of pozzolanic cements concerning the processing and composition of their constituents as well as the durability of concretes made of these cements.
In the research project, testing methods were put to the test and an evaluation concept for fresh concrete leaching was developed. The derived maximum permissible releases were significantly lower than in all applications, so that, from the research centres' point of view, there is no need for testing or regulation of fresh concrete releases.
The research activities continued the project “Low alkali cements with fly ash” (IGF 17249N) with two main targets. Firstly the effects of different characteristics of cements with fly ash on the release of aluminium into the pore solution were investigated. Secondly it was looked into how much each of the examined mechanisms (reduction of the alkali ion concentration, reduction of portlandite availability, release of aluminium into the pore solution, change of the cement stone microstructure) contributes to the prevention of a deleterious ASR.
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.
