Chopped fibres - turbobuild

Basalt Chopped Fibres are an innovative reinforcement material, designed to enhance the strength and durability of concrete by minimising cracks and improving overall structural integrity. Produced entirely from natural basalt fibres, these chopped fibres are highly resistant to corrosion, heat, and alkaline environments, making them an ideal solution for a range of industrial, commercial, and infrastructural applications.

 Key benefits of Geogrid

  • Basalt chopped fibres are specifically engineered to minimize both micro and macro-cracks in concrete, reducing the impact of shrinkage and settling during curing.

  • Unlike traditional steel fibres, basalt fibres are non-corrosive and can withstand high temperatures, maintaining up to 98% of their tensile strength at 200°C.

  • Due to their high tensile strength, less material is needed compared to other fibres, resulting in a more efficient and cost-effective solution for concrete reinforcement.

  • Basalt chopped fibres demonstrate excellent resistance to alkaline environments, making them suitable for use in aggressive conditions without deteriorating.

  • Manufactured from natural basalt fibres, these chopped fibres are non-combustible, non-toxic, and fully recyclable, supporting sustainable building practices.

Case Study: Three-Point Load Testing of Basalt Fiber Reinforced Concrete Pillar

To assess the performance of Basalt Chopped Fibres in reinforced concrete, a three-point load test was conducted at the Institute of Construction Materials, TU Dresden.

This test evaluated the effectiveness of basalt fibres in improving concrete strength and reducing crack propagation, and compared concrete beams reinforced with basalt fibres to those using traditional steel fibres.  

Under increasing loads, the basalt fibre reinforced beam showed significantly less crack opening and better load distribution, maintaining its structural integrity even as pressure increased. With only 10 kg/m³ of basalt fibres (compared to 36 kg/m³ of steel fibres), the beam exhibited superior crack resistance and durability.

The high performance at lower fibre quantities demonstrates the efficiency of basalt as a reinforcing material, as well as cost-effectiveness, making basalt fibres a compelling alternative to traditional steel reinforcements.

  • With Basalt Turbobuild reinforcement

    Reduced Crack Width
    Basalt fibres significantly limited crack development under load.

    Enhanced Load Bearing
    The reinforced beam maintained higher load-bearing capacity throughout the test.

    Less Material Requirement
    Achieved superior results using only 10 kg/m³ of basalt fibres.

    Cost-Effective Reinforcement
    Fewer fibres required compared to traditional steel, resulting in material savings.

  • With steel reinforcement

    Extensive Cracking
    The non-reinforced beam exhibited rapid crack propagation under pressure.

    Lower Load Capacity
    The beam without reinforcement failed under lower loads compared to the basalt fiber reinforced beam.

    Increased Risk of Structural Failure
    Lack of reinforcement led to reduced resilience and faster failure when subjected to stress.
