Associate Professor Hans-Dieter Beushausen

Hans Beushausen joined the University of Cape Town in 1999 after having finished his first degree in Structural Engineering at the University of Applied Sciences (HAW) Hamburg, Germany. Following his MSc degree in Structural Engineering in 2000, he obtained his PhD in 2005. He currently holds the position of Senior Lecturer in the Department of Civil Engineering, focussing his teaching efforts on the subjects of structural engineering and construction materials technology. He is a member of the Concrete Materials & Structural Integrity Research Unit (CoMSIRU) at UCT, which focuses on infrastructure performance and renewal research. His research interests include concrete durability (material aspects, durability testing, durability design and specification), performance assessment of concrete structures, repair systems for concrete structures, and bonded concrete overlays. He is Chairman of RILEM TC 230 PSC (Performance-based Specification and Control of Concrete Durability), Convener of fib TG 8.10 (Performance-based Specifications for Concrete), and an active member of the Concrete Society of Southern Africa. He has initiated and organized the successful series of ICCRRR events, the International Conference on Concrete Repair, Rehabilitation and Retrofitting, which has been held in Cape Town in 2005 and 2008, and was involved in organizing ICCRRR 2012 in connection with the 2012 RILEM Week in Cape Town. He is editor of the magazine Concrete Plant International, the international technical trade journal for the concrete producing industry and co-chairs the International Concrete Conference and Exhibition (ICCX).
