Exposure class:
Class designation |
Description of the environment | Informative examples where exposure classes may occur |
No risk of corrosion or attack | ||
XO | For concrete without reinforcement or embedded metal: all exposures except where there is freeze/thaw, abrasion or chemical attack. For concrete with reinforcement or embedded metal: very dry. |
Concrete inside buildings with very low air humidity. |
Corrosion induced by carbonation | ||
XC 1 | Dry or permanently wet | Concrete inside buildings with low air humidity. Concrete surfaces permanently submerged in water. |
XC 2 | Wet, rarely dry | Concrete surfaces subject to long-term water contact. Many foundations. |
XC 3 | Moderate humidity | Concrete inside buildings with moderate or high air humidity. External concrete, sheltered from rain. |
XC4 | Cyclic wet and dry | Concrete surfaces subject to water contact, not within exposure class XC2. |
Corrosion induced by chlorides other than from seawater | ||
XD1 | Moderate humidity | Concrete surfaces exposed to airborne chlorides |
XD2 | Wet, rarely dry | Swimming pools Concrete exposed to industrial waters containing chlorides |
XD3 | Cyclic wet and dry | Parts of bridges exposed to spray containing chlorides Pavements, sidewalks Car park slabs |
Corrosion induced by chlorides from seawater | ||
XS1 | Exposed to airborne salt but not in direct contact with seawater | Structures near to or on the coast. |
XS2 | Permanently submerged | Parts of marine structures |
XS3 | Tidal, splash, and spray zones | Parts of marine structures |
Freeze/thaw attack with or without salt | ||
XF 1 | Moderate water saturation without de-icing agent | Vertical concrete surfaces exposed to rain and freezing. |
XF 2 | Moderate water saturation with de-icing agent | Vertical concrete surfaces of road structures exposed to freezing and airborne de-icing agents. |
XF3 | High water saturation without de-icing agent | Horizontal concrete surfaces exposed to rain and freezing |
XF4 | High water saturation with de-icing agent or sea water | Road and bridge decks exposed to de-icing agents Concrete surfaces exposed to direct spray containing de-icing agents and freezing Splash zone of marine structures exposed to freezing |
Chemical attack | ||
XA1 | Slightly aggressive chemical environment | |
XA2 | Moderately aggressive chemical environment | |
XA3 | Highly aggressive chemical environment |
