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.

The future of concrete recycling is taking shape here: through the targeted sequestration of CO₂ in demolition concrete, the project is investigating an innovative approach to improving the separation of aggregate and cement stone during demolition. The optimized separation of aggregate and hardened cement paste enables the recovery of valuable secondary materials and, thus, makes an important contribution to strengthening the circular economy in the construction sector in order to achieve sustainability goals.

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.

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.

In the seminar "Digital transformation: Basics and examples from cement production" you will learn how digital technologies, in the context of Industry 4.0, are fundamentally changing the cement industry. In both Europe and the rest of the world, the industry is working towards making production processes more efficient, using resources more effectively and improving quality continuously. Data-based applications, the Internet of Things (IoT) and artificial intelligence (AI) are being used to create autonomous and intelligent systems that monitor, analyse and optimise processes in real time. These systems are used for a variety of purposes, including IoT-supported applications for process control and data acquisition, AI models for predicting production parameters, simulation tools to optimise industrial processes as well as digital twins for the virtual mapping and control of plants.

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.
