Structural Synthetic macro Fibres PP Polypropylene Fiber for shotcrete precast slabs
Description
ELITE fiber Embossed is a patented polypropylene / polyethylene
macro synthetic fiber successfully used to replace steel fibers, welded wire mesh and conventional reinforcing bars in a wide variety of applications.
Our Macro Synthetic Fibe
r compliance with ASTM C1116 OR EN14889-2 and suitable for Concrete and Shotcrete, and are specifically used to provide equivalent tensile and bending resistance to conventional reinforcement requirements.
Concrete with our Macro fiber will have three-dimensional reinforcing with enhanced flexural toughness, impact and abrasion resistance and will also help mitigate the formation of plastic shrinkage cracking in concrete.
Dosage rates will vary depending upon the reinforcing requirements and can range from 2.0 kg/m³ to 8.0 kg/m³.

Features of synthetic macro fibre
1. Provides good impact,fatigue,shrinkage control and ductility in all grade concretes.
2. Cost saving,Is easier to use,to disperse and safe to handle.
3. Can be used in highly corrosive circumstance.
4. The
surface has been embossed,which greatly improves the cohesive force between fibres and concrete,and also boosts shrinkage resistance and crack resistance.
5. 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.
Packing of synthetic macro fibre
5kg/box, 1200-1300kg/pallet, 12800kg/20' container, 25800kg/40' container.
Estimating Dosage
The dosage rate is dependent on the application however the minimum dosage range is 2kg-8kg/m3.
Typical Application
Shotcrete, and engineering industries, concrete projects,like:
1. Slab on Grade and elevated construction (distribution centers, warehouses, etc...)
2. Thin walled precast (septic tanks, vaults, walls, etc...)
3. Shotcrete for tunnel linings, pool construction and slope stabilization
4. Pavements and white-toppings
How should the fibre be used?
The fibres are wrapped with water-soluble film and uniquely packaged in water soluble paper boxes.Just throw the whole boxes of fibres into the concrete mixture, the boxes and film will dissolve within seconds, leaving the fibres to disperse evenly throughout the mixture.
