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.
"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 consortia of AC²OCem and ANICA projects held a public workshop on carbon capture technologies which was organised by VDZ on 7 - 8 March 2023.
The aim of the CLEANKER (CLEAN clinKER) project is to perform large-scale testing of this technology as an integrated method (Technology Readiness Level 7). It is planned to treat 4 000 m³/h exhaust gas in a demonstration plant to be connected to an existing kiln line at the Buzzi Unicem works in Vernasca in Italy.
Separate ultra-fine grinding of cement - Energy-efficient grinding meets optimised cement and concrete properties. Today, future-oriented cements can already be produced more sustainably and efficiently by using various components of different finenesses.
In the research project, infrared cameras are used to record the surface temperature of the clinker bed in the clinker cooler. Together with calculated enthalpy flows, this allows control room personnel to identify the operating condition of the cooler. This is used in operational tests to optimise the heat transfer in the clinker cooler by controlling the drive system and adjusting the cooling air distribution.

ACCSESS takes a cross-sectorial approach to CO₂ Capture, Transportation, Utilisation and Storage (CCUS), working with Pulp and Paper, Cement, Waste to Energy, and Biorefining, all industries with big potential for carbon dioxide removal.
One of the aims was to compile ‘Guidelines for the use of crushed sands (fine RC aggregate) in the production of cement ̓ – referred to in the project as ‘R cement ̓.
The aim was to determine systematically the granulometric influences of the main constituents Portland cement clinker (K), limestone (LL), blastfurnace slag (S) and fly ash (V) as well as the substance-specific impacts of the particle size distributions on cement, mortar and concrete properties.
The aim was to facilitate an efficient use of the new cements in high-performance and durable concretes, while taking into consideration the availabilities and origins of the cement constituents.
In this research project the additional amount of freezable water in concretes consisting of cement with several main constituents and the influence on the critical saturation of the concrete were examined.
This aim of this research project was to create a secured assessment background for testing the frost de-icer resistance of earth-moist produced concrete paving stones. The proposals could possibly be developed for testing in realistic conditions.
This research project in the field of municipal traffic areas was aimed at basic findings for a practice-oriented classification of the moisture class and the respective assessment of concrete by means of a performance-test. For this purpose concrete pavements without showing signs of a damaging ASR after approx. 10 years of use were tested. From this pavements drill cores were taken and assessed with a procedure especially developed for the moisture classes WA.
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.
The aim of the research project is the detailed investigation of the performance, durability and hydration behaviour of ternary cements with blastfurnace slag and calcined clay as main constituents (KSQ cements).
The acceptance of resource-efficient cements with significantly reduced specific CO₂ emissions is still too low in construction practice. The main reason for this is that early strength is not high enough for economical production processes and also competitive construction with concrete. Accelerating admixtures can improve the early strength of concrete. The research project investigates interactions between concrete admixtures that accelerate the strength development and cements with several main constituents.
The aim of the research project is to investigate the suitability of previously largely unused mineral secondary raw materials from the stone and earth industry as a resource-conserving and climate-friendly main cement constituent. The use of cal-cined clays from secondary raw materials instead of conventional main cement constituents or high-quality primary clays can make an important contribution to the production of climate-friendly and resource-efficient cements.
The acceptance of resource-efficient cements with significantly reduced specific CO₂ emissions is still too low in construction practice. The main reason is that the early strength is not high enough for economical production processes and competitive construction with concrete. The research project is investigating the extent to which more intensive mixing and further cement constituents besides clinker increase the mixing energy input and can increase the early cement hydration and thus the strength development.
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.
