Consideration of durability of concrete structures: Past, present, and future
Abstract The paper expresses durability in terms of the expected conditions of exposure as well as of the specified or traditional service life of structure. A brief review of deleterious actions is given. Consideration of durability means how ensuring durability is viewed by designers, and not detailed advice or rules. Thus, the paper reviews the past attitude, which relied on providing strong concrete, it being believed that durability was concomitant with strength. Changes in the properties of cement, in that, with the ‘new’ cements, the same strength as specified heretofore could be achieved at a higher water-cement ratio resulted in structures with a distinctly reduced durability. This led to a re-consideration of mix design procedures, so that both strength and durability are now explicity considered. The future approach has to rely on the use of a range of cementitious materials and admixtures and on a meticulous performance of all operations from batching to curing.
