Strength & Durability
UltraFiber 500 offers significant mitigation protection from the phenomenon of unsightly destructive plastic shrinkage cracking that can be caused by uncontrollable ambient weather conditions. This, improves the concrete durability in many respects, including significantly mitigating vulnerability to the deleterious effects of freeze/ thaw deterioration.
Cellulose is hydrophilic. This means that, unlike polypropylene and other synthetic fibers, UltraFiber 500 absorbs water and improves concrete/hydration. This makes for stronger concrete with less internal micro-cracking.
UltraFiber 500 meets ASTM and ICC standards for alkali resistance. The UltraFiber 500 fibers will not deteriorate or lose strength when exposed to high alkali environments.
