Batimix Fiber 660 - 6mm

Description

BATIMIX Fiber 660-6mm are high-performance polypropylene fibers designed specifically for secondary reinforcing of concrete. They provide optimum strength with improved resistance to cracking. They can be supplied in 12 mm length as Batimix Fiber 660-12mm and may also be available in alternative lengths.

Main Purpose

BATIMIX Fiber 660-6mm is made from carefully selected monofilaments that totally disperse into the concrete mix. Fibers are supplied in lengths of 3mm, 6mm, 9mm, and 12mm, to provide reduced cracking and long-term durability.

BATIMIX Fiber 660-12mm is used to produce concrete such as ready-mix, shotcrete, steel-reinforced, pumped, and precast. Main uses include slabs, overlays, pipes, foundations, curbs, and patch repair.

Features

Concrete prepared with BATIMIX Fiber 660-6mm is characterized by the following:

In the plastic state:

• Controlled plastic shrinkage cracks
• Minimized bleed water and segregation
• Three-dimensional reinforcing vs. two-dimension with wire mesh

In the hardened state:

• Increased flexural and tensile strengths at all ages
• a surface that is crack-free, with minimum drying and autogenous shrinkage
• Increased toughness and resistance to creep and abrasion
• Improved durability and longer service life

Properties

• Appearance : fibers
• Specific gravity : around 0.95
• Length : 12 mm
• Alkali resistance: excellent
• Water absorption: negligible

Health and Safety

BATIMIX Fiber 660-6mm is not a hazardous material. However, it should not be swallowed or come into contact with eyes. Suitable goggles should be worn. For additional information, kindly refer to the product’s Material Safety Data Sheet.

Compliance with Standards

BATIMIX Fiber 660-6mm complies with ASTM C 1116, Type III, Synthetic Fiber-Reinforced Concrete or Shotcrete. Upon request, alternative products can also be available to meet the various type requirements of ASTM C 1116.

Dosage Rates

BATIMIX Fiber 660-6mm is normally used at the rate of 0.3% to 0.8% of the cement weight, depending on the amount of strength increase and degree of cracking expected. Prior to batching, trials tests are recommended, using the actual mix composition, to assess various properties such as workability and strength.

Effect of Overdosing

An overdose of BATIMIX Fiber 660-6mm will result in an increased cohesiveness of concrete resulting from the high level of friction. This would require addition of greater amounts of superplasticizer to ensure reaching the targeted slump, which in turn may lead to some set retardation.

Compatibility

BATIMIX Fiber 660-6mm is compatible with all other Batimix admixtures incorporated in the same concrete. Concrete mixtures based on Portland cement with or without replacement materials such as silica fume, fly ash, and blast furnace slag are also compatible with BATIMIX Fiber 660-6mm.

Dispensing

BATIMIX Fiber 660-6mm can be added any time prior to the placement of concrete. However, it is preferably introduced at the batching plant during the incorporation of the cementitious phase, but it can also work well if introduced at the job site.

BATIMIX Fiber 660-6mm should be mixed with the concrete for a minimum of 3 minutes at maximum speed to ensure total dispersion and uniformity throughout the mass concrete.

Holderchem provides, upon request, technical advisory services pertaining to concrete mix designs, admixture selection, materials testing, and dispensing systems.

Storage

BATIMIX Fiber 660-6mm must be stored on a clean, dry surface under cover to avoid possible damage. Storage of propylene fibers should be done under appropriate conditions to avoid fiber deterioration. Here are some general tips for storing propylene fibers:

Temperature: Propylene fibers should be laid at a temperature between 10°C and 30°C. Higher temperatures can lead to fiber degradation.

Humidity: Propylene fibers should be laid in a dry environment to prevent moisture absorption. High humidity can weaken the fibers and reduce their strength.

UV Protection: Propylene fibers are sensitive to UV rays, which can cause fiber degradation. It is therefore important to store the fibers in a dark place or to protect them with an opaque material.

Handling: When handling propylene fibres, it is important to avoid any contact with corrosive materials or heat sources. Fibers must be handled with care to avoid damage.

Storage life: Propylene fibers have a limited storage life. It is recommended to use them within six months of receiving them. If the fibers are to be extended for a longer period, they must be protected against environmental factors such as light and humidity.

By following these tips, you can store propylene fibers in optimal conditions to ensure their quality and lifespan.
