The residential concrete slabs can benefit from the three-dimensional reinforcement provided by TenaBrix® Polypropylene synthetic microfibers.
TenaBrix® monofilament microfibers and TenaBrix® fibrillated micro fibers both can be added to residential slabs to increase concrete durability and reduce cracking in exterior and interior applications.
TenaBrix® monofilament micro fibers specifically designed to help mitigate the formation of plastic shrinkage cracking in concrete enables the concrete to develop its optimum long-term integrity and increase robustness.
TenaBrix® fibrillated micro fibers Increase surface durability, impact, and abrasion resistance when compared to plain concrete.

The specific dosage needs to be verified by laboratory trial mixing, and the concrete mixing ratio and construction environment need to be considered.
1.Priority is given to the dry mixing method: fiber+aggregate dry mixing for 30 seconds → cement/admixture mixing for 30 seconds → water mixing for ≥ 2 minutes.
2.It is forbidden to put wet material directly to avoid fiber agglomeration.
1.The vibration time is extended by 10-15 seconds to ensure uniform fiber distribution.
2.The timing of plastering needs to be advanced: finish before the first set (fibers accelerate the loss of water from the surface)
3.Avoid excessive wiping to cause fibers to float
1.When the wind speed is >5m/s or the temperature is >30℃:
✓ Immediately cover with plastic film to retain water
✓ Add 15-20% more
2.Winter construction: low-temperature-resistant modified fiber (-20 ℃ does not break)
