Specification of Chemical PVA Fiber for Cement Additive PP Fibers Concrete Admixture for Reinforcement

Chemical PVA Fiber for Cement and Concrete Support

Ringkasan Produk

Our chemical PVA (polivinil alkohol) fiber is produced use in concrete, mortir, dan beton. It functions as a high-performance admixture that increases toughness and resilience. Seratnya baik-baik saja, didistribusikan secara merata, and bond well with the cement matrix. This aids regulate fracturing and enhances effect resistance.

Rahasia Termasuk

– Kekuatan tarik tinggi : Each fiber lugs strong load-bearing capacity.
– Dispersi yang luar biasa : Fibers mix quickly into damp concrete without clumping.
– Tahan alkali : Steady in high-pH concrete atmospheres.
– Tidak korosif : Berbeda dengan serat baja, PVA won’t rust or break down over time.
– Attire length and diameter : Makes sure regular efficiency in every batch.

Spesifikasi Teknis

– Bahan: Polivinil alkohol (PVA).
– Panjang: 6 mm sampai 19 mm (alternatif standar).
– Diameter: 20– 40 mikron.
– Stamina yang kuat: ≥ 1,000 MPa.
– Perpanjangan saat putus: 6%– 8%.
– Ketebalan: 1.3 g/cm EMPAT.
– Titik lebur: Not suitable (disintegrates over 230 °C).
– pH stability: Does well in pH 12– 13.

Aplikasi

Utilize this PVA fiber in:.
– Industrial flooring.
– Precast concrete elements.
– Shotcrete and sprayed concrete.
– Memperbaiki mortir.
– Thin-section panels.
– High-performance fiber-reinforced concrete composites (HPFRCC).

The fibers change or supplement conventional support like cord mesh or steel fibers. They lower plastic contraction cracks throughout early treating and boost sturdiness after solidifying. Memadukan itu sederhana– include straight to the mixer with various other completely dry components or present during water addition. Requirement does range from 0.5 ke 2.0 kg per meter kubik beton, mengandalkan tuntutan tugas. Constantly adhere to local blending standards for ideal outcomes.

Chemical PVA Fiber for Cement and Concrete Reinforcement

More Powerful Concrete with Smart Fibers

PVA fibers are a smart option for improving cement and concrete. These artificial fibers mix well right into wet concrete. They help manage cracks that create throughout drying out and hardening. Berbeda dengan baja, Serat PVA tidak berkarat . This means longer life for your structure.

Contractors include PVA fibers to floorings, permukaan dinding, bagian, dan jalan raya. The fibers imitate tiny supports inside the concrete. They hold the material together when stress or motion occurs. This reduces surface fractures and keeps the surface area smooth. You improve durability without additional job.

Mudah Digunakan, Big Results

You can mix PVA fibers right into your normal concrete set. Tidak diperlukan alat atau langkah khusus. The fibers spread out equally and bond well with cement paste. They enhance effect resistance and strength. Even thin layers of concrete ended up being extra reliable.

These fibers also aid in shotcrete and precast job. They cut down on rebound loss throughout splashing. That saves material and time. Dan juga, they reduce the chance of plastic contraction cracks– usual issues in warm or dry climate.

Dibangun untuk Tahan Lama, Made Simple

PVA fiber admixtures offer actual worth. They boost performance while keeping prices reduced. Projects end up quicker since there’s less requirement for wire mesh or rebar in non-structural areas. Maintenance goes down over time thanks to fewer splits and less water penetration.

Whether you put walkways, dek parkir mobil, or industrial slabs, PVA fibers make concrete tougher and a lot more reputable . They meet contemporary structure needs without complicating your procedure. Simply add, mencampur, and put– more powerful results come naturally.

5 FAQs of Chemical PVA Fiber for Cement Additive PP Fibers Concrete Admixture for Reinforcement

Frequently Asked Questions About PVA Fiber for Concrete Reinforcement

Untuk apa serat PVA digunakan dalam beton?

PVA fiber is added to cement or concrete mixes to improve strength and durability. It helps control cracks that form during drying or from stress. The fibers spread evenly through the mix and hold the material together better than plain concrete.

How does PVA fiber compare to PP (polipropilen) serat?

Both fibers reduce cracking, but PVA offers higher tensile strength and better bonding with cement. PP fibers are cheaper and resist chemicals well, but they do not bond as tightly to the concrete matrix. PVA is often chosen when stronger performance is needed.

Bisakah serat PVA menggantikan tulangan baja?

TIDAK. PVA fiber works as a secondary reinforcement. It cannot carry heavy structural loads like steel bars. Namun, it reduces early-age shrinkage cracks and improves impact resistance. Gunakan bersama penguatan tradisional untuk hasil terbaik.

Berapa banyak serat PVA yang harus ditambahkan ke beton?

Dosis tipikal berkisar dari 0.6 ke 1.5 kg per meter kubik beton. The exact amount depends on the project’s needs—like crack control, kekerasan, or surface finish. Always follow the manufacturer’s guidelines or consult an engineer.

Is PVA fiber easy to mix into concrete?

Ya. PVA fiber disperses well in standard mixers without clumping. Add it during the mixing process with other dry materials or with water. Proper mixing time ensures even distribution and full performance benefits. Tidak diperlukan peralatan khusus.
