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

High-Strength PVA Fiber for Concrete Reinforcement

Tlhaloso ea Sehlahisoa

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 ho 18 mm. They are engineered to improve the performance of concrete by enhancing its toughness, crack resistance, le durability.

Likarolo tsa Bohlokoa

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. Ho fapana le likhoele tse ling tsa maiketsetso, PVA fibers do not degrade under normal concrete curing conditions.

Melemo ho Lisebelisoa tsa Konkreite

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, likotopo tsa lithanele, likarolo tsa precast, le ho lokisa seretse. 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.

Lintlha tsa Tekheniki

– Lintho tse bonahalang: Polyvinyl joala (fully hydrolyzed)
– Likhetho tsa bolelele: 3 mm, 6 mm, 9 mm, 12 mm, 15 mm, 18 mm
– Diameter: Approximately 20–40 microns
– Matla a tšepe: ≥1,600 MPa
– Modulase oa elastic: ≥40 GPA
– Botenya: ~1.3 g/cm³
– Ho hanyetsa alkali: E kgabane

Use dosage typically ranges from 0.5 ho 2.0 lik'hilograma ka mithara ea konkreite, depending on the required performance level.

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

Enhanced Crack Control

likhoele tsa PVA 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. Sena se thibela mapatso a manyenyane hore a se ke a hōla ho ba a maholo. Sephetho ke se thata haholoanyane, bokaholimo bo tšoarellang haholoanyane.

Tšusumetso e ntlafetseng le ho hanyetsa Abrasion

Concrete with PVA high-modulus fibers handles heavy use better. It resists chipping, ho ngoapa, and wear from foot or vehicle traffic. Mabato, litselana, 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, li-shotcrete linings, or precast panels often lack strength. Ho eketsa 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

Ho fapana le likhoele tse ling tsa maiketsetso, likhoele tsa PVA u se ke ua senya. 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. E ntlafatsa boima, e fokotsa ho phatloha, and increases impact resistance. Bahahi ba e eketsa fatše, lithanele, marokho, le shotcrete.

Why choose high-strength high-modulus PVA fiber?

This type of PVA fiber has strong tensile strength and stiffness. E tlamahane hantle le samente. 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.
