Polypropylene fibre for concrete crack prevention
Monofilament polypropylene fibre dispersed through the mix — it holds concrete together through its weakest 24 to 72 hours, when plastic shrinkage cracks form.
Use it for
- Controlling plastic shrinkage in fresh concrete
- Preventing micro-cracks as concrete cures
- Binding cement and sand to stop the mix segregating
- Adding to the final layer of mortar in plastering
Why this one
- Stops shrinkage cracks forming
Controls moisture loss in the first 24 to 72 hours, when concrete is most vulnerable - Avoids micro-cracks
Fibre holds the matrix together as it hydrates - Resists explosive spalling
Improved performance under fire and thermal shock - Tougher concrete
Greater impact, abrasion, and shatter resistance - Less segregation
Binds cement and sand so the mix stays homogeneous - Very high tensile strength
Over 500 MPa in a 6 mm monofilament
