製品レビュー
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, 破壊の制御, and rise toughness.
主な内容
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– 一般的にはその間にあります 6 mmと 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.
技術的特徴
– 材料 : ポリビニルアルコール (PVA).
– サイズ : 6– 12 mm.
– 直径 : 20– 40 ミクロン.
– 引張スタミナ : ≥ 1,200 MPa.
– 柔軟性弾性率 : ≥ 30 成績平均点.
– 破断伸び : ≤ 8%.
– 耐アルカリ性 : Secure in high-pH concrete atmospheres.
適用基準
Add PVA short fiber during the mixing stage. Utilize a dosage of 0.5% に 1.5% 混合物全体の体積による. 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.
保管スペースと取り扱い
ドライで買い物, trendy area far from direct sunlight. Maintain packaging sealed when not in use to prevent moisture absorption. Manage with standard construction safety and security techniques. Use handwear covers and eye security during handling.

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 に 25 厚さミリメートル. 補強なし, 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, 気候変動, and repeated loads. PVA fibers enhance toughness and resistance to influence. This suggests much less breaking, 剥離, or surface area wear in car park decks, 歩道, そして橋の床版.
より簡単な位置決め: 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.
より強力な結合: The fibers do not interfere with adhesion between the overlay and the old concrete listed below. 実は, they help preserve architectural continuity across the repair work zone. This leads to extra reputable lasting performance.
どこで活用されるか
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, it adds very little weight– 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, weak surfaces, and bad durability– without making complex the building procedure.

5 FAQs of Concrete Admixture PVA Short Fiber for Thin Layer Cement Based Overlays
よくある質問: PVA Short Fiber for Thin Layer Cement Overlays
What is PVA short fiber used for?
PVA short fiber strengthens thin cement overlays. 亀裂の形成と広がりを防ぐのに役立ちます. This makes the surface last longer and stay smoother under traffic or weather.
Why choose PVA over other fibers?
PVA fibers bond well with cement. スチールファイバーのように錆びません。. They also mix evenly without clumping. This gives better control over the final look and performance of the overlay.
How much PVA fiber should I add?
ほとんどのプロジェクトで使用されているのは、 0.6% に 1.5% セメントの重量で. Always follow the product instructions or consult your mix design. 少なすぎると十分な効果が得られない可能性があります. 多すぎると混合が困難になったり、混合が弱くなったりする可能性があります.
PVA繊維は作業性に影響しますか?
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?
はい. 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.
