Many international research efforts are and have
been underway in resolving the above listed issues.
However, most countries struggle with the implementation
of durability design guidelines, due to the many
questions yet to be answered.
In contrast, in South Africa, durability design
guidelines have been implemented in the past decade
and are nowadays frequently applied in concrete
construction. The approach has been developed to
a point where it can be used with some confidence;
however the development of the approach is ongoing
as remaining uncertainties still need to be addressed.
Based on the South African durability design
approach, some of the most common shortcomings
associated with durability design are discussed in the
following.
