Performance of two-layer concrete pavers using clinker efficient cements with focus on freeze-thaw resistance
Following the recommendations of the CO₂ roadmap, a minimum of 50 % of concrete for pavers will be produced with CEM II/C or similar clinker efficient cements by 2050. Proof of their practicability for production of two-layer pavers is still pending. This research project aims to develop actions for paver manufacturers to ensure a production of concrete pavers with a high resistance to freeze-thaw attack with de-icing chemicals using clinker efficient cements.

REDOL - Aragon's REgional Hub for circularity: Demonstration Of Local industrial-urban symbiosis initiatives
Redol deals with closing material cycles using the city of Zaragoza as an example. The research project focuses on solid urban waste, which is an abundant source to produce circular products. Five value chains for solid urban waste in the Aragon region will be redesigned in order to be able to produce circular products using an industrial-urban symbiosis approach.

Training
Energy balances and efficiency
In this training you will learn how to conduct and evaluate cement kiln and mill trials. Kiln and mill examinations are carried out in order to gather data on the performance and to validate warranty performance data such as the output, the energy consumption, input/output ratio or the efficiency. Using this data as a reliable basis, you can for example optimise individual components of the operating system as well as the cement quality, reduce energy demands as well as emissions, evaluate material cycles and reduce coating formation.

Firing alternative fuels 2026
In this training you will become familiar with all relevant aspects concerning the use of alternative fuels in cement plants. Starting with the main political drivers such as the circular economy and the European waste fuel strategy, you will get a detailed insight into the current state-of-the-art-situation with regard to the use of alternative fuels in the EU. In this context, pre-treatment and suitable quality control of alternative fuels will be also explained and presented to you. You will focus on all the relevant aspects of the use of alternative fuels in the burning process (e.g. drivers and barriers of their use, available process technology and latest developments) and discuss them in the sessions. You will acquire knowledge about technical feasibility and optimisation potential, and have the possibility to discuss case studies.

CaLby2030 – Calcium Looping to capture CO2 from industrial processes by 2030
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.

Burning technology in cement production
Clinker production is the most energy-intensive process step in cement manufacturing. It can represent up to 90% of the total energy demand in a cement plant and is therefore a main focus not only with regard to cost optimisation and quality improvement of the final product, but also regarding emission control and the reduction of impacts on the environment. VDZ’s training will enable you as participant to obtain a deeper knowledge of the clinker production process and a better understanding of how the daily decisions can impact the overall performance of the plant (quality, electrical energy use, fuel consumption and emissions).

Grinding technology in cement production
Raw material and cement grinding are the first and the last major process steps during cement production. The energy demand of these two processes amounts to up to ~70% of the electrical energy used in a cement plant. For you as participant, this training will help to obtain a better understanding of the comminution processes as well as the equipment used for grinding. The knowledge acquired in this online seminar will deliver a solid basis for assessing and evaluating the optimisation potential for grinding processes and the ground product.
