Short Fibre Reinforced Cementitious Composites and Ceramics

PD Dr. rer. nat. habil. Heiko Herrmann is senior researcher and group leader at Tallinn University of Technology (TalTech, formerly TUT). He received his degrees in Physics. The research interests of Dr. Herrmann are very diverse, ranging form complex materials to virtual reality. For over ten years his main focus lies on microstructured materials containing short fibers. In this research he combines approaches from theoretical mechanics, experiments and computer simulations. Dr. Herrmann is an alumnus of the German Alexander von Humboldt Foundation and has been participant in Marie Curie projects, coodinator of an FP7 ERG grant and principal investigator of an Estonian exploratory research grant. Professor Dr.-Ing. Jürgen Schnell was born in 1953 in Darmstadt, Germany. He studied Civil Engineering at Technische Hochschule Darmstadt and acquired his Dipl.-Ing. degree in 1979. In 1986 he reveived a doctor´s degree with a dissertation abaout concrete structuresunder the influence of low temperatures. From 1986 till 2002 he was project manager and later chief representative of an international construction group. Since 2002 he is a full professor at the Dept. „Cicil Engineering“ at Technische Universität Kaiserslautern, Germany. From 2012 to 2017 he was the head of the department Concrete and reinforced Concrete at the German Committee for Standardisation (DIN). In the years 2012-2016 he was a member of the professional council Building, Construction and Architecture of Germen Research Foundation DFG.
