Pioneers In Fiber Reinforced Concrete
PolyMacro Structure Fiber ST-42
Product Description
EESF® Macro synthetic Fiber Poly Macro ST-42 Fiber is a high-performance synthetic fiber made from virgin polypropylene (PP) or copolymer materials. It is designed to replace traditional steel mesh or steel fibers in concrete reinforcement. The black color comes from the addition of carbon black, which improves UV resistance and durability in outdoor applications. These macro fibers provide excellent crack control, impact resistance, and post-crack toughness. They are evenly dispersed in the concrete mix and do not rust or corrode, ensuring long-term performance even in aggressive environments.
Advantages
- Enhances flexural toughness and residual strength
- Improves crack resistance and impact strength
- Provides long-term durability and corrosion resistance
- UV-stable due to carbon black additive
- Easy and safe to handle compared to steel fibers
Usage
- Industrial floors and pavements
- Shotcrete and tunnel linings
- Precast concrete elements
- Marine and coastal concrete works
- Hydraulic structures such as canals, spillways, and dams
Dosage
Doses of synthetic macro fibers varies between 1.8 and 4.5 kg/m3 depending on engineering requirements of the projects.
