UltraFiber 500™ is Ideal for Precast
Concrete
UltraFiber 500™ is uniquely suited for precast concrete:
1.) Reduces Water Permeability of concrete by 67% at 50% stress loading
using 1.9 lbs/cy ( source: Dr. Nemy Banthia, University of British Columbia). Higher
doses of UltraFiber 500™ result in higher permeability reduction.
 2.)
Superior Freeze / Thaw Resistance
(see table on right)
3.) Reduces Costs
- Reduces rework by reducing cracks 85% (1.5 lbs/cy dose) compared
to no fiber
- Eliminates rejects due to WWF shadowing
(see pictures below)
- Eliminates the need for WWF for secondary reinforcement
- Compared to WWF, decreases construction time, labor, and
material cost
4.) Better Strength
- +5% to +20% better bond strength between cement paste and rebar
- +5% to +15% higher compressive strength @ 28 days
- Hydrophilic fiber provides internal curing which enhances overall hydration and concrete strength
5.) Improves Fire Resistance
6.) Enhances Decorative Finishes. No fuzz, no blemishes, no visible
surface fibers
