Executive Summary of the VDZ Study
Here you will find information about our corporate philosophy.
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.
The subject of the research project is the fine-tuning of dry cement raw materials. The focus is on the influence on the electrical energy requirement during the comminution of the raw material and the thermal effects on the subsequent clinker burning process, caused by a changed raw meal granulometry.
The IGF project 21386 N focuses on the relationship between the releasable alkali contents from aggregates and possible effects in concrete.
This In-Class Training consists of two modules: "Grinding Technology and Raw Material Preparation" (Module 1) as well as "Clinker Production and Material Technology" (Module 2). Each module has a duration of one week. The course gives a deep insight into cement production technology, covering topics from quarry operation to cement grinding.

Our Plant Maintenance and Refractories Course covers all topics concerning the high efficiency and availability of a cement plant’s key machinery. Measurement of rotary kilns and ball mills as well as independent expertise in mechanical maintenance and inspections are also among the major aspects. We also provide an extensive know-how transfer on high quality refractory kiln brick lining materials and installation including their relation to mechanical failure.
Climate protection and digitisation are key challenges for the cement industry: More than 600 representatives from the international cement industry and associated suppliers, as well as from scientific and research institutes around the world, gathered at the International VDZ Congress 2018 in Duesseldorf at the end of September. Steeped in tradition, the VDZ Congress is one of the world's most important events in the industry. The 40 talks held at this year's congress focused on particularly pressing topics such as climate protection and digitisation. The participants also discussed current technical challenges and the general situation with regard to cement production. A further highlight was an evening ceremony at which the winners of the VDZ Industrial Safety Prize 2017 received their awards.
