Petrus Jooste started his career in a structural drawing office in 1982, after completing his compulsory military training. Whilst working at Eskom as a technician, he obtained the ND Civil Eng in 1985. After working as draughtsman and model maker at various firms, he lectured at the Technical College of Johannesburg for five years. In 1997 he joined the University of Johannesburg where he lectured for the next 10 years. It was during this time that he obtained an MSc Eng from Wits for his thesis titled "Approaches to mix design and measurement of workability for self-compacting concrete". He also undertook research on rheology of concrete.

This wide academic and practical career, together with his experience as a lecturer in concrete technology and other built environment related subjects e.g. construction methods and applied mechanics, makes Petrus ideally suited for the position of senior lecturer he holds since joining the C&CI during 2008.

Matthews Magwaza was introduced to the world of cement and concrete when he joined Cement Distributors of South Africa in 1996, where he remained for seven years. He joined the C&CI in 1999 where his contribution to running thetraining laboratory, and to training in the field of pre-tertiary education was invaluable. He had developed his knowledge of cement and concrete to the extent that he is now a valuable lecturer in the department. His ability to speak five African languages has made him a popular asset to the School, as he is able to offer explanations and answer questions from learners in a language they understand.
