Specification of Pva polyvinyl alcohol high-strength high modulus fiber 3-18mm vinylon cement concrete

High-Strength PVA Fiber for Concrete Reinforcement

Product Overview

This product is a high-strength, high-modulus polyvinyl alcohol (PVA) fiber designed specifically for use in cement and concrete. The fibers come in lengths ranging from 3 mm kuti 18 mm. They are engineered to improve the performance of concrete by enhancing its toughness, crack resistance, uye kusimba.

Key Features

The PVA fibers have excellent tensile strength and a high elastic modulus. This means they can carry heavy loads without stretching too much. Their surface is treated to bond well with cement paste, which helps transfer stress evenly throughout the mix. The fibers disperse easily in concrete without clumping, ensuring uniform distribution. They resist alkali attack from cement, so they stay strong over time. Kusiyana nemamwe mafiber ekugadzira, PVA fibers do not degrade under normal concrete curing conditions.

Benefits muConcrete Applications

Adding these fibers to concrete reduces early-age plastic shrinkage cracks. They also control crack width in hardened concrete, which improves long-term durability. Structures made with PVA fiber-reinforced concrete show better impact resistance and flexural performance. This makes them ideal for industrial floors, tunnel linings, precast zvinhu, uye kugadzira madhaka. The fibers replace or reduce the need for steel mesh in many applications, saving labor and cutting costs. Mixing is simple—just add the fibers during batching like any other admixture.

Technical Details

– Material: Polyvinyl doro (fully hydrolyzed)
– Length options: 3 mm, 6 mm, 9 mm, 12 mm, 15 mm, 18 mm
– Diameter: Approximately 20–40 microns
– Kusimba simba: ≥1,600 MPa
– Elastic modulus: ≥40 GPa

Applications of Pva polyvinyl alcohol high-strength high modulus fiber 3-18mm vinylon cement concrete

Applications of PVA Polyvinyl Alcohol High-Strength High-Modulus Fiber (3–18 mm) in Vinylon Cement Concrete

Enhanced Crack Control

PVA fibers are added to cement concrete to reduce cracking. These short fibers (3–18 mm long) spread evenly through the mix. They hold the material together when stress builds up. Izvi zvinomisa mitswe midiki kukura kuita mikuru. Mhedzisiro yacho yakaoma, more durable surface.

Yakavandudzwa Impact uye Abrasion Resistance

Kongiri ne PVA high-modulus fibers handles heavy use better. It resists chipping, scratching, and wear from foot or vehicle traffic. Floors, pavements, and industrial slabs last longer because the fibers absorb energy and keep the structure intact under pressure.

Better Performance in Thin Sections

Thin concrete elements like overlays, shotcrete linings, or precast panels often lack strength. Kuwedzera 3–18 mm PVA fibers gives them extra support without needing steel mesh. The fibers bond well with cement paste, making these lightweight sections strong enough for real-world demands.

Suitable for Repair and Retrofit Work

Older concrete structures often need fixing. Vinylon-reinforced concrete works well for patching and strengthening. It sticks firmly to existing surfaces and moves with them as temperatures change. This reduces delamination and improves the life of repairs.

Environmentally Stable and Safe

Kusiyana nemamwe mafiber ekugadzira, PVA fibers do not corrode. They stay stable in wet or alkaline conditions inside concrete. They also do not release harmful substances, making them safe for indoor and outdoor use alike. Their compatibility with standard mixing and placing methods means no special tools or training are needed.

5 FAQs of Pva polyvinyl alcohol high-strength high modulus fiber 3-18mm vinylon cement concrete

Frequently Asked Questions About PVA Polyvinyl Alcohol High-Strength High-Modulus Fiber (3–18mm) for Cement and Concrete

What is PVA fiber used for in concrete?

PVA fiber strengthens cement and concrete. It improves toughness, kunoderedza kutsemuka, uye inowedzera simba rekudzivirira. Vavaki vanowedzera kune pasi, tunnels, mabhiriji, uye shotcrete.

Why choose high-strength high-modulus PVA fiber?

This type of PVA fiber has strong tensile strength and stiffness. Inobatanidza zvakanaka nesamende. That means better crack control and longer service life for structures.

What length should I use—3mm, 6mm, or up to 18mm?

Short fibers (3–6mm) work well in thin layers or plaster. Medium lengths (9–12mm) suit standard concrete mixes. Long fibers (15–18mm) give more reinforcement in heavy-duty applications like industrial slabs.

How much PVA fiber do I add to concrete?

Typical dosage is 0.5 ku 2.0 kg pa cubic mita yekongiri. Mari chaiyo inoenderana nezvido zveprojekiti. Always follow mix design guidelines or consult an engineer.

Is PVA fiber safe and easy to mix?

Ehe. PVA fiber is non-toxic and safe to handle. It disperses evenly in mixers without clumping. Hapana midziyo yakakosha inodiwa. Ingoiwedzera panguva yekusanganiswa kwemaitiro.
