Professor Mark Alexander
BSc (Eng), MSc (Eng), PhD (Witwatersrand), Pr Eng, FSAICE, FSAAE, MICT, MASSAf, Fellow UCT
Mark Alexander is Professor of Civil Engineering in the University of Cape Town. He teaches and researches in cement and concrete materials engineering, with experience in fundamental and applied research relating to design and construction. He is part of the leadership of CoMSIRU at UCT, where work is being done on problems of marine concrete durability, amongst others.
Professor Alexander has published extensively both in South Africa and abroad. He is President of RILEM, an international organisation concerned with research in materials and structures. He is also Chairman of the Cement and Concrete Institute of South Africa. In addition, he acts as a specialist consultant on concrete materials and related problems. Furthermore, he is a Fellow of the South African Institution of Civil Engineering, the South African Academy of Engineering, the University of Cape Town, and RILEM.
