Concrete is the backbone of modern construction—but even the strongest concrete has its limits. Cracks caused by shrinkage, freeze-thaw cycles, and repetitive loading can severely affect long-term durability and safety. This is where synthetic fiber reinforcement enters the scene.

Today, we explore three high-performance solutions developed to meet different technical demands in concrete applications: ConFib MF Microfibers, ConFib FB Microfibers, and ConFib Macro-48.

🧬 Why Use Synthetic Fibers in Concrete?

Unlike traditional steel reinforcements, synthetic fibers offer:

• Corrosion-free performance
• Easy integration during mixing
• Crack control from the plastic stage onward
• Enhanced ductility and post-crack load capacity
  These fibers act as internal support systems—microscopically or structurally—depending on their design.

🔍 ConFib MF Microfibers: Precision at Micro Level

ConFib MF Microfibers are mono-filament polypropylene fibers, designed to combat early-age cracking such as plastic shrinkage and settlement. With a density of over 50 million fibers per cubic meter, they form a micro-mesh throughout the concrete matrix.

Key Benefits:

• Reduces plastic and drying shrinkage cracks
• Increases freeze-thaw and abrasion resistance
• Improves shotcrete cohesion and finish

Use Cases: Screed, repair mortar, plaster, precast, and surface hardeners

🧩 ConFib FB Microfibers: Fibrillated Network Strength

ConFib FB fibers are micro-fibrillated, meaning they open into net-like structures within the mix. This design increases the concrete’s mechanical cohesion, making it more resilient and uniform during application.

Key Benefits:

• Reduces segregation and improves mix stability
• Enhances surface durability and fatigue resistance
• Extends service life under cyclic loading

Use Cases: Industrial slabs, rail infrastructure, precast elements

💪 ConFib Macro-48: Replacing Steel, Empowering Structure

Macro-48 is a structural macro fiber designed to replace steel mesh or rebar in many concrete applications. Its 48 mm length and 600 MPa tensile strength give concrete significant post-crack integrity and impact resistance.

Key Benefits:

• Provides primary reinforcement
• Eliminates need for steel handling on-site
• Improves crack bridging and residual strength
• Reduces rebound loss in shotcrete

Use Cases: Tunnel linings, coastal concrete, steel deck slabs, precast panels

🧪 Backed by Standards

All ConFib fiber products comply with:

• EN 14889-2 (European Fiber Standard for Concrete)
• ASTM C1116/C1609 (US Flexural and Residual Strength Standards)

These testing procedures ensure product quality, repeatability, and verified concrete enhancement.

✅ Conclusion: Tailored Reinforcement for Every Concrete Mix

From micro-level crack prevention to structural-grade toughness, ConFib synthetic fibers address every challenge conventional concrete faces. Whether your goal is durability, safety, or cost-effectiveness, integrating the right fiber into your concrete mix can revolutionize the final product.

Concrete alone is strong—fiber-reinforced concrete is smarter.
