Increasing energy efficiency in the cement industry through training by means of virtual reality (VR)
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
"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.
AC²OCem - Accelerating Carbon Capture using Oxyfuel Technology in Cement Production
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.
CLEANKER – Integrated calcium looping process for CO₂ capture
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.
Development of a method to improve clinker cooling and to increase energy efficiency in cement rotary kilns by using infrared cameras
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.
Optimisation of clinker-efficient cements by means of multimodal particle size distributions using energy-efficient products from separate ultra-fine grinding
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.
Process engineering investigation of the energetic-material utilisation of wastes containing carbon fibres in cement plants - EVCAZ
In the AiF project EVCAZ, the energetic and material utilisation of wastes containing carbon fibres is to be demonstrated on an industrial scale in a cement plant. The central tasks are the evaluation of the conversion success of the CF fibres, the recording of the resulting emissions and the consideration of influences on the process and the clinker quality. The findings obtained are summarised to assess health and environmental risks and to answer questions relevant to approval as a decision-making aid for cement plant operators.
Cement clinker production with simultaneous power generation
The core concept of the research project is to generate the maximum amount of electrical energy from the process exhaust gas during the production of cement clinker without affecting its kiln capacity or clinker quality. The electricity generated should cover the base load requirements for the cement production.
Durability of concretes with clinker efficient cements under modified concrete technological conditions
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.
Proof for durability of chemically stressed concretes and concrete components: Proof of concrete attacked by carbonic acid
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.
Testing the freeze-thaw resistance with de-icing agents of concrete for exposure class XF2
Environmentally friendly railway sleepers with calcium sulfoaluminate cements
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.

Analysis concept for the determination of trace elements in the eluate of cement-bound building materials (IGF No. 16989 N)
Interactions between siliceous fly ash or calcined clay as cement main constituent and superplasticizers based on polycarboxylate ether as well as their influences on rheological properties of fresh cement paste and fresh concrete
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.
