Concrete Covers - Europe

 

The concrete cover is the distance between the surface of the reinforcement closest to the nearest concrete surface (including links and stirrups and surface reinforcement where relevant) and the nearest concrete surface.  (chapter 4.4.1.1.(1) from EN1992-1-1). The main role of concrete cover thickness is avoiding corrosion of steel in concrete.

- The nominal cover […] is defined as a minimum cover, cmin (see 4.4.1.2), plus an allowance in design for deviation, ∆Cdev (see 4.4.1.3):  cnom = cmin + ∆Cdev

 

- The value of ∆Cdev […] the recommended value is 10 mm (4.4.1.3.(2) from EN1992-1-1)
