What is the difference between Type 1 and Type 2 steel fibers?

Type 1 Steel Fibers

- Step 1: Type 1 steel fibers are typically manufactured using a cold-drawing process, which results in a smooth surface.- Step 2: These fibers are usually straight and have a round cross-section, providing high tensile strength and excellent ductility.- Step 3: Type 1 steel fibers are commonly used in concrete applications to improve the toughness and impact resistance of the material.- Step 4: These fibers are also known for their ability to inhibit crack formation and propagation in concrete structures.

Type 2 Steel Fibers

- Step 1: Type 2 steel fibers are manufactured using a different process called micro-alloying, which gives them a textured surface.- Step 2: The fibers have a wavy or corrugated shape with a non-uniform cross-section, providing enhanced bond strength with the concrete matrix.- Step 3: Type 2 steel fibers are often utilized in precast concrete elements or shotcrete applications where a strong bond between the fiber and the matrix is crucial.- Step 4: These fibers are known for their ability to increase the flexural and shear strength of concrete, making them ideal for applications that require high durability.In conclusion, the main difference between Type 1 and Type 2 steel fibers lies in their manufacturing process, surface texture, shape, and application in concrete. Type 1 fibers are straight, round, and smooth-surfaced, offering improved toughness and crack control in concrete. On the other hand, Type 2 fibers are wavy, textured, and used for enhancing bond strength and mechanical properties in specific concrete applications. Both types of steel fibers play a vital role in improving the performance and durability of concrete structures.
