Vöruskoðun
PVA short fiber is a high-performance artificial fiber made from polyvinyl alcohol. It is particularly created for use in thin layer cement-based overlays. These overlays are typically put on fix or safeguard concrete surfaces. The fiber helps boost strength, stjórna brotum, and rise toughness.
Lykill Inniheldur
The fiber has outstanding bond strength with concrete matrices. It withstands alkali assault, which prevails in concrete settings. Each fiber is reduced to an exact size– oftast á milli 6 mm og 12 mm– to make sure even distribution in the mix. The surface area of the fiber is treated to improve adhesion with the surrounding concrete paste. This leads to much better crack resistance and lowered contraction.
Tæknileg einkenni
– Efni : Pólývínýl alkóhól (PVA).
– Stærð : 6– 12 mm.
– Þvermál : 20– 40 míkron.
– Togþol : ≥ 1,200 MPa.
– Sveigjanlegur stuðull : ≥ 30 Meðaleinkunn.
– Lenging í broti : ≤ 8%.
– Alkalíviðnám : Secure in high-pH concrete atmospheres.
Umsóknarstaðlar
Add PVA short fiber during the mixing stage. Utilize a dosage of 0.5% til 1.5% miðað við rúmmál af heildarblöndunni. Mix completely up until fibers are evenly spread. Prevent clumping by adding fibers gradually while the mixer is running. This item works well in spray-applied or trowel-finished overlays as slim as 5 mm. It works with many concrete kinds, consisting of Portland concrete and blended cements. Do not make use of with hostile chemical admixtures without prior screening.

Why Use PVA Short Fiber?
PVA brief fiber is a synthetic fiber included in cement-based overlays. It considerably enhances the performance of thin-layer applications. These overlays are typically only 10 til 25 millimetrar á þykkt. Án styrkingar, such thin layers can break quickly under stress or shrinking. PVA fibers assist control these fractures from developing and spreading out.
Key Advantages in Actual Projects
Better Split Control: PVA fibers develop a dense network inside the overlay. This network holds the product with each other also when tiny fractures show up. The outcome is a surface that stays undamaged longer and looks much better with time.
Greater Resilience: Thin overlays deal with rush hour, climate modifications, and repeated loads. PVA fibers enhance toughness and resistance to influence. This suggests much less breaking, spjöllun, or surface area wear in car park decks, gangstéttir, og brúarþilfar.
Auðveldari staðsetning: Unlike steel mesh or bigger fibers, PVA brief fibers mix equally into the cement without clumping. Employees can apply the overlay smoothly with trowels or spray devices. There’s no demand to position or safeguard extra support on-site.
Sterkari tenging: The fibers do not interfere with adhesion between the overlay and the old concrete listed below. Reyndar, they help preserve architectural continuity across the repair work zone. This leads to extra reputable lasting performance.
Þar sem það er notað
Specialists use PVA-fortified overlays in several settings. Usual instances consist of restoring worn industrial floorings, resurfacing aging freeways, and fixing airport terminal paths. The approach works well for both interior and exterior tasks. Because the overlay is slim, það bætir mjög litlum þyngd– ideal for structures where tons limits matter.
PVA brief fiber transforms ordinary concrete overlays right into high-performance repair service options. It fixes real problems like cracking, veikt yfirborð, and bad durability– without making complex the building procedure.

5 FAQs of Concrete Admixture PVA Short Fiber for Thin Layer Cement Based Overlays
Algengar spurningar: PVA Short Fiber for Thin Layer Cement Overlays
What is PVA short fiber used for?
PVA short fiber strengthens thin cement overlays. It helps stop cracks from forming and spreading. This makes the surface last longer and stay smoother under traffic or weather.
Why choose PVA over other fibers?
PVA trefjar tengjast vel sementi. They do not rust like steel fibers. They also mix evenly without clumping. This gives better control over the final look and performance of the overlay.
Hversu mikið af PVA trefjum ætti ég að bæta við?
Flest verkefni nota 0.6% til 1.5% miðað við þyngd sements. Always follow the product instructions or consult your mix design. Of lítið hjálpar kannski ekki nóg. Of mikið getur gert blöndun erfiða eða veikt blönduna.
Hefur PVA trefjar áhrif á vinnuhæfni?
A small amount of PVA fiber has little effect on workability. The mix stays easy to spread and finish. If you add more fiber, you might need a water reducer or superplasticizer to keep it smooth.
Can I use PVA fiber in wet or dry mixes?
Já. PVA short fiber works in both wet-mix and dry-mix systems. Just make sure the fiber disperses fully during mixing. Good dispersion means even strength and fewer weak spots in the hardened overlay.
