Concrete is a material that has been used successfully and in a variety of ways for centuries. For this reason, Martina Schnellenbach-Held and her team at the University of Duisburg-Essen undertake detailed studies of this material.A high-performance aerogel concrete (HPAC) was developed in cooperation with the Institute of Materials Research at the German Aerospace Center (DLR) by embedding fused-quartz aerogel granules into UHPC matrices. This novel material meets the requirements of the Energy Conservation Ordinance (EnEV) in single-shell applications even using comparatively small component thicknesses accommodating construction-relevant compressive strengths.
In her lecture, Martina Schnellenbach-Held described the research conducted to develop suitable concrete formulas and a concept for manufacturing concrete cogwheels and roller bearings
Univ.-Prof. Dr.-Ing. Martina Schnellenbach-Held worked as a structural engineer in civil and construction engineering and as a project, group and construction manager in building construction for Philipp Holzmann AG at its Düsseldorf headquarters.
As a university professor, she has been head of the Institute of Concrete and Masonry Structures of the University of Duisburg-Essen since April 2004.
