Description
Adfil®Ignis fibres have been used in many projects globally, primarily to provide passive fire protection to the concrete structure in segmental tunnel linings, sprayed or cast in-situ concrete. This product has been proven to control explosive spalling in concrete exposed to fire.
Explosive spalling occurs when moisture in a concrete structure is superheated and turns to steam. Pressure builds up inside the concrete and results in an explosive failure of the exposed face. Adfil®Ignis 1812 will start to melt when the heat generated is approximately 165°C. When the temperature reaches 360°C, the fibres vaporise to leave millions of capillaries in the concrete which allow the steam to escape.
Application areas
Adfil®Ignis 1812 fibres are applied in a wide range of applications. Examples include sprayed linings, precast segments, and in-situ concrete for:
- Road and rail tunnels
- High rise buildings
- Cable tunnels
- Bridges
- Underground/multi storey car parks
Benefits
- Dramatically reduces explosive spalling
- Improves resistance to plastic shrinkage cracks
- Improves hardened state benefits, such as abrasion and impact resistance
Packaging
- 1kg water soluble bags
