How to evaluate the performance of steel fibers?

1、 Tensile strength

It is an important indicator for evaluating the performance of steel fibers, which determines their load-bearing capacity under stress. The higher the tensile strength, the better the performance.

2、 Length, wire diameter, and aspect ratio

The longer the fiber length, the more difficult it is to pull it out of the concrete; The smaller the fiber diameter, the more dispersed it is in the concrete; The aspect ratio is the ratio of length to wire diameter, and the larger the aspect ratio, the stronger the performance of the fiber. Hengfeng adhesive steel fiber has a super large aspect ratio and strong reinforcement effect.

3、 Anchor method

The end hook shape of Hengfeng steel fibers can provide better anchoring and effectively suppress fiber pull-out, thereby enhancing performance.

4、 Bending performance

Reflects the toughness of steel fibers when subjected to bending forces. Hengfeng steel fiber requires that the sample be bent twice without breaking.
