Polyfibra
Polyfibra it is a multifilamentous fiber made of 100% virgin polypropylene. Designed as secondary reinforcement in concrete and mortars. Specified to reduce cracking due to plastic contraction in the fresh state of the concrete and due to temperature in its hardened state.
Description
Specified to reduce cracking due to plastic contraction in the fresh state of the concrete and due to temperature in its hardened state.
Benefits
In plastic concrete:
- Reduces shrinkage cracking.
- Reduces segregation.
- Reduces bleeding water.
- Provides three-dimensional reinforcement.
- Reduces temperature cracking.
- Reduces permeability.
- Increases bending resistance.
- Increases resistance to direct tension.
- Increases resistance to cutting and torsion.
- Increases impact resistance.
- Quick and easy placement because it is mixed with concrete.
- Allows very quick demolding.
- A clean and polished surface is achieved.
