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 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.
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.
As part of the IGF research project 17364 N funded by the AiF, studies were performed in conjunction with the research institute of the cement industry (FIZ) and the Institute of Chemical and Electrochemical Process Engineering at Clausthal University (ICVT) on the catalytic reduction of CO and organic components in the rotary kiln exhaust gas of cement plants.
The main aim of the research project was to evaluate the influence of oxygen enrichment on the clinker, on kiln operation and on the use of alternative fuels as well as on the composition of the exhaust gas.
At the request of VDZ members with business interests in Russian-speaking regions, VDZ therefore got together with other service providers and universities in early 2013 to work on creating a platform for training courses in Russian in the field of cement production and utilisation.
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 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 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.
