Results: Cement chemical optimisation of cements containing fly ash
Environmental Data of the German Cement Industry 2019
VDZ's environmental data reflect that the German cement industry invests decisively in plant optimisation. This keeps them in a leading role worldwide in terms of environmental compatibility, alternative fuels and plant energy efficiency.
LeptoCalc – Recovery of fines from concrete recycling plants as cement constituent
The use of fines from concrete recycling plants as cement constituents is currently insufficiently investigated and requires further research. The basic prerequisite for the utilisation of the fines will be to be able to characterise the material properties as quickly and comprehensively as possible and to ensure a constant material flow. An essential part of the research project is therefore the development of a rapid test method with which the properties of these fines can be estimated, among other things, by measuring the residual reactivity.
Performance of ternary cements with Portland cement clinker, granulated blast furnace slag and calcined clay as the main constituents
The aim of the research project is the detailed investigation of the performance, durability and hydration behaviour of ternary cements with blastfurnace slag and calcined clay as main constituents (KSQ cements).
Environmentally friendly railway sleepers with calcium sulfoaluminate cements
The research project will investigate whether the technical requirements for railway sleepers with CSA cements can be realised. Also, some basic links to standards (e.g. modulus of elasticity, creep and shrinkage in accordance with EC2) must be checked and ensured.
Process Technology of Cement Production
This course consists of two modules: "Raw Material Preparation and Grinding Technology" (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.
Basic Course Process Control
This course gives the participants the opportunity to learn how to handle a cement plant control system and to understand the influence of process parameters on the cement manufacturing process.
Plant Maintenance and Refractories Course
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. In addition, we provide an extensive know-how transfer on high quality refractory kiln brick lining materials and installation including their relation to mechanical failure.
International­ VDZ Congress 2018
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.
