Fibre Reinforced Shotcrete with Fibre Rebar combines two important elements in concrete construction: fibre rebar and fibre shotcrete. Fibre rebar refers to the use of reinforcing bars made from fibrous materials, such as carbon or glass fibres, while fibre shotcrete involves the addition of fibres to the shotcrete mixture.

Fibre rebar is a type of reinforcement that offers several advantages over traditional steel rebar. It provides high tensile strength and stiffness while being lightweight, making it easier to handle and transport. Fibre rebar is also corrosion-resistant, eliminating the risk of rust and reducing long-term maintenance requirements. Additionally, fibre rebar has excellent dimensional stability and is non-magnetic, making it suitable for applications where electrical or magnetic fields are a concern.

Fibre shotcrete, on the other hand, refers to the application of shotcrete—a concrete mix that is pneumatically projected at high velocity—combined with the addition of fibres. The fibres in the shotcrete mixture enhance its mechanical properties and performance. Common types of fibres used in fibre shotcrete include synthetic fibres, such as polypropylene or polyvinyl alcohol, as well as metallic fibres like steel or stainless steel.

The combination of fibre rebar and fibre shotcrete offers synergistic benefits in concrete construction. Fibre rebar provides structural reinforcement, improving the tensile and flexural strength of the concrete. It helps control cracking and enhances the overall durability of the structure. Fibre shotcrete, on the other hand, enhances the toughness and impact resistance of the concrete, making it more resistant to dynamic loading and reducing the risk of spalling or surface erosion.

By incorporating both fibre rebar and fibre shotcrete, the resulting construction material exhibits enhanced strength, crack resistance, and durability. This combination is particularly beneficial in applications where high-performance concrete is required, such as in tunnels, underground structures, slope stabilization, or seismic-resistant construction.

Stainless steel fibres for concrete Technical Parameters

Main Functions:

The tensile strength and flexural strength of concrete can be increased by 20%-50% and 40%-80% when appropriate steel fiber is added to concrete. Under the usual fiber dosage, impact compression toughness can be increased by 2-7 times, impact shear, tensile toughness can be increased by several times to dozens of times. Because of the crack resistance and integrity of steel fiber concrete, the freeze-thaw resistance, heat resistance, wear resistance, cavitation resistance and corrosion resistance have been significantly improved. Concrete collective itself is a kind of multi-phase, multi-component, non-uniform granular brittle composite material, its compressive ratio is only about one tenth, crack resistance is very low.The addition of steel fiber prevents the initiation of cracks and reduces the size and number of cracks. In the process of loading, the extension and expansion of cracks are inhibited, and the stress and concentration of cracks are alleviated.
