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 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.

EMSARZEM analyses the processing and utilisation of waste incineration ashes, which are produced during the thermal recycling of municipal waste.

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).

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.

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.
