Viscous-row steel fibers are processed by bonding individual steel fibers into rows using water-soluble glue, aiming to improve the construction performance of steel fiber reinforced concrete. Its characteristics are mainly reflected in aspects such as production process, physical properties, construction convenience, and application advantages.

Production Process and Structural Design: The steel fibers are processed and shaped using a cold-drawing technique, typically featuring end-hooked, wavy, or other shaped cross-sections. The fiber length is generally between 30-65 millimeters, with a diameter ranging from 0.5-1.0 millimeters, and an aspect ratio of up to 40-80. During production, the fibers are bonded into rows using water-soluble glue. This structure effectively prevents clumping during mixing, ensuring uniform dispersion.

Physical properties and mechanical advantages: The viscose-coated steel fibers exhibit high strength and excellent toughness, with a tensile strength reaching beyond 600-1000 MPa and an elastic modulus exceeding 400 GPa. Their end-hook shape induces an anchoring effect in concrete, significantly enhancing the bond strength, thereby improving the crack resistance, impact resistance, and fatigue resistance of the matrix material. When incorporated into concrete, it can increase the compressive strength by 10%-80% and the tensile strength by 50%-100%.

Construction Convenience and Dispersibility: The viscose-coated steel fibers are resistant to clumping during the addition and mixing process, exhibiting good dispersibility and facilitating simple construction operations. The water-soluble glue dissolves during mixing, ensuring uniform distribution of the fibers and reducing construction difficulty. Additionally, the rebound rate can be kept below 10% in the wet shotcreting process, making it suitable for various construction methods such as dry or wet shotcreting.

Application advantages and cost-effectiveness: The viscous steel fibers can significantly enhance the integrity and durability of concrete structures, making them suitable for applications such as road, bridge, tunnel, and building repairs. Their uniformly distributed nature reduces crack width, enhances seismic and blast resistance, and the small cross-section of each fiber makes them less prone to corrosion issues. Additionally, this product is cost-effective, and its performance after recycling is close to that of conventional products, contributing to reduced production energy consumption.
