Ø 2．Rebar partially or completely no needed anymore, or reduce the diameter of steel bar for1~2mm;

Ø 3．Construction cycle shortened by 25%, suitable for projects where continuous and fast concrete placing is required;

Ø 4. Mixing as conventional concrete, no extra equipment needed.

Main Functions:

Different types of fibers used in concrete, each with its own distinct advantages and applications. Here are some common types of steel fibers and their benefits:

Steel Wire Fibers: Steel wire fibers are a common type of steel fiber, typically ranging in diameter from 0.25 millimeters to 1 millimeter. Their advantages include enhancing the tensile strength and toughness of concrete, effectively controlling crack propagation, and improving the durability and longevity of the concrete. Additionally, steel wire fibers provide excellent impact resistance and fatigue performance, making them suitable for structures subjected to heavy loads and dynamic loads.

Shear Steel Fibers: Shear steel fibers are steel fibers with a bent shape, and their advantage lies in increasing the shear strength and crack resistance of concrete. Due to their shape, which allows effective anchorage within the concrete, shear steel fibers can prevent crack propagation and enhance the overall strength and durability of structures. This type of steel fiber is particularly suitable for structures that need to resist shear forces, such as underground engineering and tunnels.

Steel Fiber Bundles: Steel fiber bundles consist of multiple steel wires bundled together to form a reinforcing material. The advantage of steel fiber bundles is that they provide higher tensile strength and better crack control. As the steel wires in the fiber bundle can work together to form a stronger reinforcing network, steel fiber bundles are particularly useful in structures that require higher strength and stricter crack control.

Macro-Synthetic Fibers: Macro-synthetic fibers are fibers made from synthetic materials such as polypropylene or polyester fibers. Their advantages include providing good crack resistance, increasing the toughness and durability of concrete, and resisting freeze-thaw cycles and chemical attacks. Additionally, macro-synthetic fibers have high durability and fatigue resistance, making them suitable for various structures and applications.
