EXPOSURE CLASSES
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. |
| Chemical attack |
| XA 2 |
Moderately aggressive chemical environment. |
Concrete exposed to chemical attack from natural soils or ground water (special studies of environmental conditions may be required). |
| XF 3 |
High water saturation without de-icing agent. |
Horizontal concrete surfaces exposed to rain and freezing. |
FIRE RESISTANCE CLASSES
REI 60 – 60 minutes
REI 90 – 90 minutes
STORAGE OF SLABS
During the storage of hollow core slabs the following requirements must be observed:
- Only store items on a compacted ground
- Max. height of stacked slabs shall not exceed 2.0 m
- The slabs shall be separated by placing wooden beams 300-400 mm from the end of the item
- Wooden beams shall be placed exactly one over the other and shall not be shorter than the breadth of the slab
