Description
Bagged cement is shipped in paper or woven bags where bulk handling is impractical. At around 0.75 m3/t it is a deadweight cargo. The whole of its care is keeping it dry, because cement sets and is ruined by water, alongside managing dust and the breakage of heavy bags.
Stowage & loading
Bags are stowed on dunnage in clean, dry holds, blocked into a stable stow, with torn bags set aside. Dryness is paramount, since any wetting sets the cement hard and ruins it, and wet-weather loading is tightly controlled. Dust escaping from bags is managed during handling.
Hazards & handling
The dominant hazard is moisture: wetted bags set hard and are a total loss, and condensation or leaks can spoil the stow. Cement dust from torn bags is a nuisance and irritant, and the heavy bags are prone to breakage, spreading dust and product and weakening the stow.
Carriage & discharge
The holds are kept dry and free of leaks and condensation, with the stow watched for any wetting, which is the key to delivering the cement sound. Discharge is by sling or fork; set or wetted bags are segregated and noted, and dust and residue cleaned on completion.
Key hazards
- Sets hard and is ruined if bags are wetted
- Cement dust as a nuisance and irritant from torn bags
- Bag breakage weakening the stow
Loading precautions
- Stow on dunnage in clean, dry holds and keep the cargo dry
- Set aside torn bags and manage wet-weather handling
- Control dust from bags during handling
Stowage factors are indicative and vary with grade, origin, moisture and packing. Always verify against the shipper's cargo declaration and the applicable IMSBC Code schedule before fixing or loading. This is general information, not professional or safety advice.
