KESSY, J G; ALEXANDER, M G  and  BEUSHAUSEN, H. Concrete durability standards: International trends and the South African context. J. S. Afr. Inst. Civ. Eng. [online]. 2015, vol.57, n.1, pp.47-58. ISSN 2309-8775.

Durability problems in reinforced concrete (RC) structures are an issue of global concern, since they threaten economic growth, natural resources and human safety. As a result, attempts have been made in design standards developed in most countries to include requirements to provide durable RC structures. This paper examines and compares such durability requirements in standards from the United States, Australia, Canada, Europe, India and South Africa. It focuses on aspects such as exposure conditions, limiting values of material compositions and proportions, and cover depth to the reinforcing steel. The paper describes issues behind prescriptive standards and deals with challenges confronting performance approaches for concrete durability. Following international trends, it is evident that the South African Standards, particularly SANS 10100-2, must undergo substantial updating and improvements to durability requirements. The paper suggests the means of re-drafting and implementing durability specifications in any revised version of SANS 10100-2, taking into account both prescriptive and performance alternatives. Further, a methodology of developing durability specifications suitable for the South African concrete industry is proposed, and recommendations are made for future developments.

Keywords : durability; concrete standards; specifications; performance-based; SANS.
