- High yield
- Good stability - therefore lower formwork effort
- Does not cause corrosion on concrete steel reinforcements
- Has a neutral effect on PVC cables
- Suitable for pumping and for manual application
- Resistant to ageing
- Very good surface adhesion to steel, concrete, masonry
Proof of Performance
- Wall and ceiling ducts, fire-resistant 120 minutes Z-19.53-2298
- Wall and ceiling openings, fire-resistant Z-19.53-2499
Clean the opening and pre-wet the component reveal
Premix dry cement. First add water, then mortar into the mixing container. Mix for 3 minutes at 300-400 rpm.
Installation of fire protection mortar: Panel over larger ducts on one side.
Installation of post-installation wedges for subsequent installation.
Affix ID plate.
For post-installation: Use a hammer to remove the post-installation wedges.
Re-install cable: Seal remaining opening.
| The following dimensions are required for the application of fire protection mortar: | Technical data | Yield | |
| Wall bulkhead | Ceiling bulkhead | ||
| Minimum thickness of component | see system A and B system specification | see system A and B system specification | |
| Max. bulkhead size: Width Height/length | |||
| Minimum work space from cable duct to upper component reveal | |||
| Spacing between cable ducts (horizontal) | |||
| Minimum spacing between cable ducts (vertical) | |||
| Minimum spacing to next bulkhead | |||
| Raw material basis | Cement and mineral aggregates | Application temperature | ≥ 5 °C |
| Shelf life | at least one year | Flexural strength | approx. 0.8-1.5 N/mm2 |
| Mixing ratio | 10 kg: 3 litres | Processing time | approx. 60 minutes |

- Wall and ceiling ducts, fire-resistant 120 minutes Z-19.53-2298
- Wall and ceiling openings, fire-resistant Z-19.53-2499
Application area
For processing in the system [A] + [B] + [G2] + [H] + [B2] + [F] + [F2] + [G3] + [H1] + [H2] + [H3]
- Combination partition [A]
- Fire partition M[B]
- Pipe partition dB [G2]
- Pipe partition Z [H]
- For sealing wall and ceiling ducts with a fire resistance rating of fire-resistant and S 120 in accordance with DIN 4102, part 9, for cables, cable bundles, cable support systems and combination partitions
- The sealing allows all kinds of electrical cables and wires (including fibre optic cables), cable bundles, cable support systems, single waveguides, single wires for control purposes, electrical installation pipes, flammable and non-flammable pipes to be used. Special applications such as hydraulic hoses, double solar tubes, air-conditioning split lines, vacuum lines, pneumatic lines and gas lines are possible.
Instructions
- Add approximately 6 litres of water to a 20 kg bag, approximately 3 litres of water to a 10 kg bucket
- 20 kg of dry mortar gives about 20 L of wet mortar
