Profile
The Chair of Mineral Processing of Building Material and Reuse was founded in 1995 at the Civil En-gineering Department. It is led by Ms. Prof. Dr.-Ing. habil. Anette Müller since this time.
The key activities in research and development of the chair are:
- mineral processing of primary and secondary raw materials
- physical and granulometric evaluation of the processing products
- recycling possibilities of Construction and Demolition Waste (CDW) resp. industrial residues as well as the development of new products
- functional product properties of wastes and by-products
Activities
Three main thematic foci are continuously worked on and deepened in the research:
- Rough and fine grinding of primary and secondary raw materials and of recycled building materials
In connection with the build-up of closed material circuits resp. the utilization of wastes as raw material substitutes, comminution of materials is the crucial technological step. In a multiplicity of accomplished investigations at the chair, on the one hand the coarse comminution was the central point of work, in order to examine the suitability of broken building debris as an aggregate for re-cycling concrete. On the other hand fine powders, ground in laboratory mills or in a ball mill with an air classifier have been accomplished. The determination of the reactivity of comminuted mate-rials due to the dispersity and the fabrication of new products were carried out. - Granulometric characteristics for disperse systems relevant for building material
The characteristics of bulk materials such as particle size distribution, particle shape distribution, specific surfaces by Blaine and BET or density can be measured in a modern equipped laboratory for particle technology. For a broad range of raw materials, building materials and residual substances, used in the building industry, the particle size distributions were experimentally intended as well as comparative, methodical investigations with different measuring procedures accomplished. - Product development from building wastes and industrial residual substances
Utilization ways for construction waste, separated construction waste components, power station ashes, etc. are designed and experimentally tested. The development first of all aims at residual substances for which there are no or only inferior operational areas so far, to convert them into products which a high quality level. With the existing recycling laboratory and the pilot plant station, excellent experimental capacities are available for this topic.
The pilot plant station offers all conditions with its extensive machine equipment, in order to accom-plish mechanical treatment processes for production in the semi technical scales.
A considerable number of research topics have been worked on or are currently under examination at the chair. Funding authorities are the German Research Council, the Federal Ministry of Education and Research, the Federal Ministry of Economics and Technology, the Thuringia’s Ministry of Science, Research and Art as well as the Deutsche Bundesstiftung Umwelt.
Further, detailed information to the chair, e.g. finalized or current research projects, publications, a list of cooperation partners, etc. can be found at our university's website.
