Abstract:
Concrete cover is defined as the distance between the outermost surface of embedded reinforcement and the closest outer surface of the concrete. For flat or single plane formwork, providing the proper cover is fairly straightforward considering the appropriate tolerances. The issue becomes more complex when considering architectural rustication, reveals, or drip grooves on the concrete surface. Architectural formliners further complicate the issue because of the multiple amplitudes likely present on the form surface. In all cases, the concrete cover to the embedded reinforcing steel must be properly considered on the concrete surface. This article examines these concrete cover issues as they affect some basic structural elements.
