Environmental impact class:
| Marking of classes | Environmental description | Common environmental classes informative examples |
| No risk of corrosion or aggression | ||
| XO | Concrete without armature or nested details: all operating environment, with the exception of those with refrigeration and heating, erosion and chemical effects.
For concrete with reinforcement or metal inserts: very dry. |
Concrete inside buildings with very low humidity. |
| Carbonation corrosion | ||
| XC 1 | Dry or always humid | Concrete inside buildings with low air humidity. Concrete in water. |
| XC 2 | Humid, rarely dry | Long soaking concrete surfaces in the water. Many of the foundations. |
| XC 3 | Average humidity | Concrete inside buildings with average or high air humidity.
Outside, concrete is covered from the rain. |
| XC4 | Cyclically humid and dry | Concrete surfaces soaking in water but doesn‘t belong to XC2 class. |
| Chlorides but not by sea water caused corrosion | ||
| XD1 | Average humidity environment | Open concrete surface splashed by chlorinated water spray. |
| XD2 | Humid, rarely dry | Swimming pools. Open concrete, exposed by industrial chlorinated water. |
| XD3 | Cyclically humid and dry | Bridge parts, which are splashed with chlorinated water Pavings, sideways Car parking boards. |
| Seawater chloride corrosion | ||
| XS1 | Working salt spray, but not direct sea water | Structures near the shore or on shore |
| XS2 | Constantly immersed | Marine parts of structures |
| XS3 | Flood, splashing and splattering area | Marine parts of structures |
| Cooling / heating effect with or without salt | ||
| XF 1 | Average water absorption without de-icing material | Vertical concrete surfaces, exposed by rain and cold. |
| XF 2 | Average water absorption with de-icing material | Verical concrete sufaces of road construcion, exposed by cold and de-icing salt. Road construction vertical concrete surfaces exposed by the cold and de-icing salt. |
| XF3 | High water absorption without de-icing material | Horizontal concrete surfaces, exposed by rain and cold. |
| XF4 | High water absorption with de-icing material or sea water | Road and bridge surfaces exposed by salt Concrete surfaces directly exposed by salt and frost Cold exposed structure in sea spray zone. |
| Chemical exposure | ||
| XA1 | Low chemical aggressivity environment | |
| XA2 | Average chemical aggressivity environment | |
| XA3 | High chemical aggressivity environment | |
Ammount of chlorides in concrete mixture:
~ 0.2 % from cement mass.
