Pva Fibres Concrete

The effect of uncoated polyvinyl alcohol pva fibre addition on dynamic properties of fibre reinforced concrete frc has been investigated in the current study.

Pva fibres concrete.

Pva fibres of two geometric lengths 6 and 12 mm with aspect ratio of 428 and 857 respectively were utilised. Rms702 by nycon are ultra fine pva fibers polyvinyl alcohol for use in creating fiber reinforced concrete frc. Pva fibbers polyvinyl alcohol are high performance reinforcement fibres for concreteand mortar. Rsc15 by nycon are 8 denier ductile mono filament pva fibers polyvinyl alcohol for use in creating fiber reinforced concrete frc advantages light weight 1 3 density high finishability small denier translucent monofilament increased flexural and tensile strength increased impact and abrasion resistance shrinka.

Unlike steel pva fibers develop a molecular and chemical bond with the cement during hydration and curing. Fibers include steel fibers glass fibers synthetic fibers and natural fibers each of which lend varying properties to the concrete. It contains short discrete fibers that are uniformly distributed and randomly oriented. Fiber reinforced concrete frc is concrete containing fibrous material which increases its structural integrity.

These fibers are commonly used in very thin applications where moisture and ductility are important. In addition the character of fiber reinforced concrete. High performance fibers made of pva which is short for polyvinyl alcohol were developed some 20 years ago by kuraray a japanese company. Effect of polyvinyl alcohol pva fibre on dynamic and material properties of fibre reinforced concrete december 2013 construction and building materials 49 374 383.

Pva fibers are a new high performance fiber for concrete. Pva fibers polyvinyl alcohol are high performance reinforcement fibers for concrete and mortar. Like steel these pva fibers have high tensile strength and a greater modulus of elasticity than regular concrete. When added to concrete or mortar the fibers develop a molecular and chemical bond with the cement during hydration and curing.

Pva fibers are well suited for a wide variety of applications because of their superior crack fighting properties high modulus of elastici. Pva fibers are well suited for a wide variety of applications because of their superior crack fighting properties high modulus of elasticity excellent tensile and molecular bond strength and high resistance to alkali uv chemicals fatigue and abrasion.
