콘크리트 혼화제의 요구 사항: PVA Short Fiber for Thin Layer Cement-Based Overlays

제품 리뷰

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, control fracturing, and rise toughness.

주요 내용

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– 일반적으로 그 사이에 6 mm 및 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.

기술적 특성

– 재료 : 폴리비닐알코올 (PVA).
– 크기 : 6– 12 mm.
– 지름 : 20– 40 미크론.
– 인장 체력 : ≥ 1,200 MPa.
– 유연한 계수 : ≥ 30 평점 평균.
– 휴식시 신장 : ≤ 8%.
– 알칼리 저항 : Secure in high-pH concrete atmospheres.

적용기준

Add PVA short fiber during the mixing stage. Utilize a dosage of 0.5% 에게 1.5% 전체 믹스의 양에 따라. 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.

Applications of Concrete Admixture PVA Short Fiber for Thin Layer Cement Based Overlays

Applications of Concrete Admixture PVA Short Fiber for Thin Layer Cement-Based Overlays

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 에게 25 밀리미터 두께. 강화 없이, 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, 깨짐, or surface area wear in car park decks, 보도, 그리고 교량 데크.

더 쉬운 포지셔닝: 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.

더 강한 결합: The fibers do not interfere with adhesion between the overlay and the old concrete listed below. 실제로, they help preserve architectural continuity across the repair work zone. This leads to extra reputable lasting performance.

활용되는 곳

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

자주 묻는 질문: PVA Short Fiber for Thin Layer Cement Overlays

What is PVA short fiber used for?

PVA short fiber strengthens thin cement overlays. 균열이 생기고 퍼지는 것을 막는 데 도움이 됩니다.. 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. 강철섬유처럼 녹슬지 않습니다.. They also mix evenly without clumping. This gives better control over the final look and performance of the overlay.

PVA 섬유를 얼마나 추가해야 합니까??

대부분의 프로젝트에서 사용 0.6% 에게 1.5% 시멘트 중량 기준. Always follow the product instructions or consult your mix design. 너무 적으면 충분하지 않을 수 있습니다.. 너무 많으면 혼합이 어려워지거나 혼합이 약해질 수 있습니다..

PVA 섬유가 가공성에 영향을 미치나요??

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?

예. 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.
