Steel Fiber for Concrete (Hooked-End / Straight / Wavy)

The recommended dosage of steel fiber varies by application. For shotcrete, it is generally 30-50 kg/m³; for industrial floors, 20-40 kg/m³; for bridge deck pavement, 40-80 kg/m³; for water conservancy engineering, 30-60 kg/m³. The specific dosage should be determined by testing according to engineering design requirements and concrete mix proportions. We can provide technical support.

Hooked-end steel fiber has hooks at both ends, providing stronger mechanical interlocking with the concrete matrix, better bonding performance, and more significant strengthening and toughening effects. It is suitable for projects with high requirements for toughness and crack resistance. Straight steel fiber has a smooth surface and relatively weaker bonding performance, but is lower in price and suitable for general reinforcement projects. Wavy and indented types fall between the two.

Steel fiber can be directly put into the concrete mixer and mixed evenly with cement, aggregate, water, etc. To prevent steel fiber from balling, the following methods are recommended: 1) evenly scatter during mixing; 2) use a steel fiber dispersing machine; 3) use water-soluble glue-bonded steel fiber bundles. Mixing time should be appropriately extended to ensure even dispersion of steel fiber.
