Basalt Fiber for Concrete

Acid and alkali resistant, resistant to breakage, durable

Tenabrix is China’s leading basalt fiber manufacturer. Tenabrix™ basalt fiber chopped strands are a specially developed steel fiber reinforcement material for use in cement concrete/mortar. As a secondary reinforcement material, it can significantly improve the toughness, flexural strength, and impermeability of concrete.

What is Tenabrix™ basalt fiber?

Tenabrix™ Basalt fiber is a continuous fiber produced by drawing molten basalt rock at temperatures between 1450°C and 1500°C through a spinning die at high speed. Similar to glass fiber, its properties fall between high-strength S-glass fiber and alkali-free E-glass fiber. Pure natural basalt fiber typically appears brown, with some varieties exhibiting a golden hue.

Model: 17μm-22μm-9mm,12mm,15mm,18mm

Basalt fiber chopped strands applied in cement concrete/mortar are a specially developed steel fiber-like reinforcement material. As a secondary reinforcement material, it significantly enhances concrete’s toughness, flexural tensile strength, and water resistance. It can replace traditional materials such as steel fibers, polypropylene, and polyacrylonitrile, making it suitable for cement concrete projects like roads, bridges, and dams. It offers superior performance and high cost-effectiveness.

Maximize Concrect with the Benefits of Tenabrix Basalt Fiber

Enhance the toughness of concrete.

Basalt fiber possesses inherent high strength and high elastic modulus properties, forming a three-dimensional network support structure within concrete. This effectively addresses the inherent brittleness and susceptibility to fracture in concrete.

Improve pavement resistance to thermal deformation.

Basalt fiber exhibits excellent resistance to both high and low temperatures. Its thermal expansion coefficient closely matches that of concrete, effectively coordinating the volume deformation of concrete during temperature fluctuations.

Improve pavement impermeability.

Basalt fibers are uniformly distributed within the concrete matrix, filling microscopic pores and capillary channels to form a dense, impermeable barrier that effectively blocks the penetration of water, rain, and harmful substances.

Enhance the shear strength, crack resistance, and fatigue resistance of concrete

Basalt fibers exhibit excellent interfacial bonding strength with concrete, effectively transferring stress and synergistically enhancing the material’s mechanical properties.
