Concrete Society Seminar - Concrete Durability Unpacked

Structural engineers and specifiers are increasingly required explicitly to consider durability for reinforced concrete structures. Locally and internationally, new durability specifications are making an appearance which require measurable properties of the concrete to be assessed. This seminar provided a platform to bring practitioners up to date on developments in durability specifications and implementation.

This seminar was intended to reach an audience of consulting engineers, contractors and suppliers (including admixtures and readymix concrete). It was a unique opportunity for these delegates to build on their knowledge on how best to specify and produce concrete that will maintain its original form and serviceability when exposed to adverse environments.

Compared to the previous durability seminars attendance was well down, but better than expected in these difficult times in which the industry, as a whole, is finding itself. A total of 152 people attended around the country.


The seminar was chaired by Prof Mark Alexander, President of the Concrete Society and featured well-known and respected experts giving presentations. The proceedings were interactive and practical, with delegates being encouraged to raise questions and issues of concern.
Proceedings ended with an open panel session of Questions & Answers that was in general very lively and informative.





The programme covered the following main topics and speakers:

» Background to concrete durability
|  Bryan Perrie, The Concrete Institute

» Main durability issues in SA
|  Mark Alexander, President, CSSA and Emeritus Professor, UCT

» The Client’s perspective
|  Edwin Kruger, SANRAL

» Designing for durability and strength
|  Philip Ronné, Aecom

» Practical ways of achieving durability on site
|  George Evans, PPC

» Series of case studies of implementation
|  Panel of the above
