Teräskuidut

Teräskuidut are metallic fibers made from steel. They are commonly used as reinforcement in concrete and other cementitious materials to improve their mechanical properties. The addition of steel fibers to concrete can significantly enhance its tensile strength, flexural strength, and toughness, while also reducing cracking and spalling. This makes them suitable for a wide range of applications, including industrial floors, bridge decks, precast elements, and tunneling.

The properties of teräskuidut, such as their shape, aspect ratio (length to diameter), and surface texture, are designed to optimize their interaction with the cement matrix. Different types of steel fibers exist, including hooked-end, crimped, and straight fibers, each offering specific advantages in terms of anchorage and distribution within the concrete. The dosage of steel fibers used in concrete mixtures can vary depending on the desired performance characteristics.

The use of teräskuidut is a well-established practice in civil engineering, offering an effective way to create more durable and resilient concrete structures. They contribute to enhanced performance under static and dynamic loads, as well as improved resistance to impact and abrasion. Research continues to explore new applications and further optimize the use of steel fibers in construction materials.
