Macro Fiber Reinforcement for Concrete – Cost, CO₂ and Construction Efficiency

Macro fiber reinforcement for concrete is an alternative to traditional steel reinforcement that reduces cost, CO₂ and construction complexity. MiniBars™ offers a fundamentally different approach to concrete reinforcement.

Instead of placing steel bars or mesh, reinforcement is distributed throughout the concrete matrix using high-performance composite macro fibers based on basalt or alkali-resistant glass fibers.

This enables a more efficient, durable and cost-effective way to design and build concrete structures.

Why engineers and contractors choose MiniBars™:

  • Corrosion-free reinforcement – no risk of rust or durability loss
  • Reduced or eliminated need for concrete cover
  • Lower structural weight and optimized design
  • Faster production and simplified construction process
  • Improved crack control and durability
  • Reduced lifecycle maintenance costs

Reduced CO₂ and material usage

Steel reinforcement requires protective concrete cover to prevent corrosion. This increases both material usage and CO₂ footprint. Because MiniBars™ does not corrode, this protective layer can often be reduced or eliminated depending on the application.

This leads to:

  • Reduced concrete volume
  • Lower CO₂ footprint
  • More efficient transport (more elements per truck)
  • Improved sustainability and LCA performance

Construction efficiency and cost savings

Traditional reinforcement requires:

  • Cutting and bending steel
  • Transport and handling
  • Placement and tying of reinforcement

With MiniBars™, reinforcement is mixed directly into the concrete at the batching plant.

This can result in:

  • 80–100% reduction in steel fixing operations
  • 40–60% reduction in labour
  • Up to 50% faster installation
  • 30–50% shorter project timelines

While the price per kg of MiniBars™ is higher than traditional fibers, the required dosage is significantly lower. In many applications this results in comparable or lower total reinforcement cost per m³ of concrete.
