Steel Fiber: Superior Reinforcement for Concrete Applications

Fibre d'acier is a reinforcement material widely used in construction to enhance the mechanical properties of concrete. It improves structural strength, reduces crack widths, and increases resistance to impact and abrasion.

Fibres d'acier come in various types, including glued hooked-end fibers, copper-coated micro steel fibers, and brass-coated hooked-end fibers. Each type offers unique bonding characteristics and mechanical anchorage within the concrete matrix.

Fibres d'acier are typically added directly to the dry concrete mix. Ensure thorough mixing to achieve uniform fiber distribution, which is crucial for optimal performance.

The optimal dosage varies based on project requirements. Consulting with a structural engineer or referring to manufacturer guidelines can help determine the appropriate amount for your specific application.

In certain specific circumstances, fibre d'acier can entirely replace traditional steel reinforcement bar (“rebar”) in reinforced concrete. This is most common in industrial flooring but also in some other precasting applications. Typically, these are corroborated with laboratory testing to confirm that performance requirements are met. Care should be taken to ensure that local design code requirements are also met, which may impose minimum quantities of steel reinforcement within the concrete.
