Twisted Macro-Synthetic Fiber
TenaBrix® Twisted Macro Synthetic Fiber is a high-performance fiber composed of a blend of polypropylene and polyethylene resins, specifically engineered to enhance the durability and performance of conventional concrete, pre-cast concrete, and shotcrete. Its unique twisted bundle design creates a strong mechanical bond with the concrete matrix, providing tensile and bending properties comparable to traditional steel reinforcement. This innovative fiber significantly improves crack resistance and toughness, making it an ideal replacement for steel fibers in fiber-reinforced concrete, while optimizing the overall structural integrity of the material.

Key Features
- Superior Crack Control: Twisted macro-synthetic fibers effectively manage cracks caused by shrinkage, temperature fluctuations, or load stress by distributing stress more evenly throughout the concrete, preventing the formation of large cracks.
- Enhanced Toughness: These fibers bridge cracks, providing additional support, allowing the concrete to absorb more energy before failure, which significantly improves the toughness of the concrete.
- Excellent Corrosion Resistance: Unlike traditional steel fibers, synthetic fibers do not corrode, making them especially suitable for use in corrosive environments.
- Reduced Construction Costs: Compared to traditional rebar placement, twisted macro-synthetic fibers are easier to mix into concrete, significantly reducing construction time and labor costs.
