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 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 current research project aims to determine if CEM II/C-cements can be used in some exposure classes (XC1-4, XF1) according to DIN 1045 2 under modified technological conditions of the concrete (reduced water-cement ratio, increased minimum strength class) without additional requirements.
In order to be able to use new, clinker-efficient cements and concretes in the future even under the attack of carbonic acid, the development of a test and assessment concept is necessary. Therefore, VDZ and the Institute for Building Research of the RWTH Aachen started a joint research project.
The aim of the research project is to develop a practical method for testing the freeze-thaw resistance of XF2 concretes.
The research project will investigate whether the technical requirements for railway sleepers with CSA cements can be realised. Also, some basic links to standards (e.g. modulus of elasticity, creep and shrinkage in accordance with EC2) must be checked and ensured.
The objective of the URBCON project is to reduce the consumption of primary raw materials and CO₂ emissions resulting from the construction and maintenance of buildings and infrastructure in urban areas. The project focuses on concrete as a building material.
The overriding aim is to actively promote innovative developments on future-oriented markets in Germany. The building industry is one of these.
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.
