Fiber added to concrete is a technique that involves incorporating fibers into the concrete mixture to enhance its mechanical properties and performance. One type of fiber commonly used is polymer fiber, which is made from synthetic materials such as polypropylene or polyvinyl alcohol. When these polymer fibers are added to the concrete mix, they disperse throughout the matrix, providing reinforcement and improving the overall strength and durability of the polymer fiber concrete.

Polymer fiber concrete, also known as fiber-reinforced concrete, is a composite material that combines the benefits of both polymers and fibers. The fiber added to concrete mix enhances its tensile strength, flexural strength, impact resistance, and crack resistance. The fibers act as a reinforcement, helping to distribute the stresses within the concrete and preventing the propagation of cracks.

The use of polymer fiber concrete offers several advantages over traditional concrete. Firstly, it improves the toughness and ductility of the concrete, making it more resistant to cracking and enhancing its ability to withstand dynamic loads. This is particularly beneficial in applications where the concrete is subjected to heavy traffic, vibrations, or seismic activity.

Additionally, polymer fibers in concrete can enhance its durability by reducing shrinkage and controlling the formation of microcracks. By improving the resistance to cracking, polymer fiber concrete exhibits increased resistance to moisture penetration, freeze-thaw cycles, and chemical attack, resulting in a longer service life.

Moreover, the fiber added to concrete can also improve the workability and cohesiveness of the concrete mix, making it easier to handle and place. This is particularly advantageous in complex concrete structures or areas with congested reinforcement.

PP fiber Description

The fibres are Made of Polypropylene.

PP fiber concrete Features

Ø Provides good impact,fatigue,shrinkage control and ductility in all grade concretes.

Ø Cost saving,Is easier to use,to disperse and safe to handle.

Ø Can be used in highly corrosive circumstance.

Ø The surface has been embossed,which greatly improves the cohesive force between fibres and concrete,and also boosts shrinkage resistance and crack resistance.

Ø The toughness of macro synthetic fibre is less stronger than steel fibre.But test has shown slabs on grade and pre-cast concrete predominately require a dosage rate of between 25kg-40kg of steel fibres per cubic meter, in comparison,using between 3kg-10kg of macro synthetic fibre per cubic meter of concrete. Synthetic fibres achieve greater strength and ductility in the matrix.

PP staple fiber Estimating Data

The dosage rate is dependent on the application however the minimum dosage range is 3kg/m3-10kg/m3.

Typical Application

Shotcrete, and engineering industries, concrete project,like being used in base,ground, bridge, dam, especially where relatively large-scale deformations may be expected, such as in mining engineering environment.

Polypropylene fiber reinforced Technical Information

Packing

5kg/box, 1200-1300kg/pallet, 12800kg/20’ container, 25800kg/40’ container.

How should the fibre be used-- SAP 65S

The fibres are wrapped with water-soluble film and uniquely packaged in paper boxes.Then just throw the whole boxes of fibres into the concrete mixture, the boxes and film then dissolve within seconds, leaving the fibres to disperse evenly throughout the mixture.
