Ore Pass Lining materials are pre-bagged high impact and abrasion resistant concrete mixes used for the construction and repair of ore passes.
Advantages
- Ore Pass Lining offers different wear resistant aggregate components to allow specific abrasion or high impact characteristics to be met.
- Ore Pass Lining mix design allows easy mixing and placing with minimal vibrating required.
- Early strength gains, if correct water/cement ratios are used, allow fast turnaround of formwork.
- Additional accelerators are not required to achieve strength gains.

Storage
Materials should normally be stored under cover. Reduced shelf life may occur if packaging is exposed to the elements. Packaging materials may deteriorate, allowing moisture ingress into the cementitious binder. This could lead to premature hardening.
Shelf Life
Ore Pass Lining products will store for up to 6 months in dry conditions.
Safety
| General | The use of eye protection, gloves and dust masks is recommended. Follow the typical precautions as prescribed for handling Portland cement. |
| Inhalation | Constant exposure over long periods of time to very high concentrations may cause a cough with phlegm. |
| Skin contact | Prolonged exposure could sensitize skin causing mild irritation. In extreme cases, dermatitis could occur. |
| Eyes | Use eye protection. However, if eyes become affected, irrigate eyes with copious amounts of clean water. Seek medical attention. |
| Ingestion | Ingestion of harmful quantities is unlikely to occur. If ingested, drink copious amounts of drinking water and consult a medical practitioner. DO NOT INDUCE VOMITING. |
