Durability is defined in relation to definite exposure conditions, and this is recognized in current codes which allow different depths of cover and different qualities of concrete for varying exposures; in those codes, quality is assessed in terms of compressive strength, and validity of this assumption is discussed; other assessments of durability are reviewed; where requirements of durability restrict freedom of design, alternative means of achieving satisfactory life may be considered; it is concluded that, while compressive strength is reasonable guide to concrete quality and its variation, cement content, low water/cement ratio, permeability, entrained air and depth of cover must also be considered.
