Synthetic fiber for concrete
Synthetic fibers for concrete are reinforcement materials made from synthetic materials such as polypropylene, polyethylene, nylon, or polyester. Synthetic fibers for concrete are used to enhance the performance and durability of concrete. Synthetic fibers for concrete disperse stress, control cracking, and improve the concrete's tensile strength and impact resistance. Synthetic fibers for concrete are easy to mix and construct, and they find wide application in areas like industrial floors and shotcrete. By adding synthetic fibers, the lifespan of concrete can be extended while reducing maintenance costs.
Product Detail

Synthetic fibers for concrete are reinforcement materials made from various synthetic materials, such as polypropylene, polyethylene, nylon, or polyester. These Synthetic fibers for concrete are added to concrete mixes to improve its performance and durability. Here are some key points about synthetic fibers for concrete:

Types of Synthetic fibers for concrete: There are different types of synthetic fibers used in concrete, including monofilament fibers, fibrillated fibers, and macro-synthetic fibers. Each type has its own properties and benefits.

Reinforcement Benefits: Synthetic fibers for concrete enhance the mechanical properties of concrete by improving its tensile strength, flexural strength, impact resistance, and crack control. Synthetic fibers for concrete act as a secondary reinforcement system, distributing stress and preventing crack propagation.

Durability Enhancement: Synthetic fibers for concrete improve the durability of concrete by reducing the formation and propagation of cracks. Synthetic fibers for concreteenhance the concrete's resistance to shrinkage, thermal cracking, and plastic settlement.

Workability and Mixing: Synthetic fibers for concrete are typically added directly to the concrete mix during batching. Synthetic fibers for concrete are easy to mix and disperse, and they do not require special equipment for installation.

Applications: Synthetic fibers for concrete are widely used in various concrete applications, including industrial floors, pavements, shotcrete, precast elements, and overlays. Synthetic fibers for concrete are particularly beneficial in applications where traditional reinforcement methods are difficult or impractical.

Fiber Length and Dosage: The length and dosage of synthetic fibers depend on the specific application and desired performance. Manufacturers provide guidelines and recommendations for fiber length and dosage based on the project requirements.

Compatibility and Testing: It is important to ensure the compatibility of Synthetic fibers for concrete with the concrete mix and to conduct proper testing to verify their performance in specific applications. This includes testing for fiber dispersion, bond strength, and impact resistance.

macro fibers Description

The fibres are Made of Polypropylene.

Macro Synthetic Fiber Features

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

Ø Cost saving,Is easier to use,to disperseand 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.

macro synthetic fiber reinforced concrete Estimating Data

The dosage rate is dependent on the application however the minimum dosage range

is 3kg/m3-10kg/m3.

macro fiber concrete reinforcement 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.

How should the fibre be used--PP50

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.
