The purpose of the research project is to gain the first systematic scientific findings on spalling behaviour in the event of fire and on thermo-mechanical and thermo-physical properties for concretes with the new clinker-efficient cement types and with recycled aggregates.

As plans are progressing for the CCUS infrastructure for transporting, storing and using CO₂, it is becoming increasingly clear that the separated CO₂ must be very pure in order to be used or stored. CC technologies are currently being planned with considerable engineering effort and electricity consumption for gas cleaning systems to separate unwanted accompanying substances. This is where this project comes in. It aims to investigate an innovative concept that could significantly reduce this effort.

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.

With us, you can expand your knowledge around the production of cement and lime, as well as in the area of concrete technology. As a competent partner, we have been offering our customers individual qualification solutions since 2010. In addition to German-language online courses, we also offer English- and Russian-language courses and other services.

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).

This online seminar equips you with the knowledge and tools needed to systematically evaluate CO₂ capture technologies applied to industrial processes such as the clinker burning process. You will be introduced to the key benchmarking methodology and will learn how to assess technical performance, economic feasibility, and site-specific applicability in a structured way. Through practical examples and case studies, you will see how data-driven benchmarking can support informed decision-making on the path toward climate-neutral production.

The 9ᵗʰ International VDZ Congress took place in Düsseldorf on 6 – 8 November 2024. The VDZ Congress is the international scientific forum for the cement industry and its suppliers. Delegates from all over the world discuss the latest developments concerning the transformation of the industry on its way towards climate neutrality.
