Fatigue resistance of steel fiber compared with ordinary concrete, the flexural and compressive fatigue properties of steel fiber reinforced concrete are greatly improved. For example, when the bending fatigue life is 106 times, the stress ratio of steel fiber reinforced concrete with 1.5% fiber content is 0.68, while that of ordinary concrete is only 0.51. When the stress ratio is 0.7, the bending fatigue life of steel fiber reinforced concrete exceeds 105 times, while that of ordinary concrete is only 850 times. Another example is: when the compressive fatigue life of steel fiber reinforced concrete with 2% fiber reaches 2*106 times, the specific force can reach 0.92, while the stress ratio of ordinary concrete is only 0.56. It can be seen that the use of steel fiber reinforced concrete can significantly improve its fatigue life in projects bearing fatigue loads such as pavement and pier.

USER'S GUIDANCE Dosage: depend on the application and minimum dosage is 20kg/㎥-70kg/㎥ Mixing: When pouring sand and aggregates into the hopper, mix an appropriate amount of loose steel fibers evenly, and then add cement. Put it in a mixing table, dry and mix for 2 minutes. If it is glued in rows of steel fibers, you need to add steel fibers after adding water so that the water can dissolve the bonding glue. Put the uniformly mixed fiber concrete into the conveyor and transport. Concrete pouring and laying should be compacted. The Safety & Packaging of SDS-05035 0.50mm Diameter 35mm Length Hooked End Steel Fiber Star Smith is a professional steel fiber manufacturer that can offer a wide range of steel fibre types that meets different needs. Packaging: 20kg or 25kg per bag/carton or as your requirements, there are 50 bags or 1000kg in a pallet, 24tons per 20'container. And the pallets should be waterproof, don't stack pallets on top of each other. Gloves and eye protection should be used when adding the steel fibers.

Hooked end steel fiber was made of high-quality cold drawn steel line, in order to make sure that it has high tensile strength and animal tolerance. And the steel fiber in bulk ensures the mixing fast and convenient, and the distribution homogeneous. During pulling from the cement, the steel fiber hooked end is deformation slowly it is considered to be the best anchorage force. Unlike conventional reinforced fiber, steel fibers focus on three-dimensional reinforcement and make it impossible for a plain crack to follow. Advantages of Loose Hooked End Steel Fiber Technology advantage The design of end hooks at both ends of steel fiber is the best anchoring design, which slowly deforms in the process of drawing, thus enhancing the binding force between steel fiber and concrete. Material advantage SDS steel fiber is made of high-quality cold drawing wire, and its tensile strength is greater than 1100MPa, which ensures extremely small tolerance and high tensile strength. Economic advantage A.Compared with ordinary concrete, the same mixing and construction, do not need to add equipment. B.Under the same strength, the concrete consumption can be saved C.Replace or partially replace reinforcement D. Shorten the construction period, especially suitable for large projects requiring continuous and rapid pouring of concrete.

The steel fiber for concrete reinforcement is a new kind of metal material, in order to enhance concrete and shotcrete in its hardened state. Tengzhou SDS steel fibers make concrete have extremely high flexural strength and shear strength, and have good toughness, crack resistance, earthquake resistance, seepage control and other functions. Widely used in industrial factory floor, highway, high-speed rail, bridge, airport, tunnel, water conservancy, electric power, municipal engineering, etc. The steel fiber manufacturer has passed ISO9001 certification, and its products are exported to Southeast Asia, Europe, America and etc. The Formation of Steel Fiber Steel fibers are defined in ASTM A820 as pieces of smooth or deformed fibers that are sufficiently small to be dispersed at random in a concrete mixture. ASTM A820 designates tensile requirements, dimensions and permissible variations. There are mainly 4 steps for steel fibers based on our production process: Raw Material Dry Drawing Glued stampling & Forming The Benefits of Steel Fiber For the same mixing and construction, there is no need to add equipment or increase the construction cost. Under the same strength requirement, it can replace steel mesh and reduce the pouring thickness of concrete by 15-25%. Improve the construction conditions, mixing vehicles and construction personnel can reach the site directly, and shorten the construction period by 30%. Steel fiber reinforced concrete has high tensile strength, which can prolong the distance between contraction joints and facilitate continuous and rapid pouring of concrete. Convenient construction, saving labor, greatly shortening the construction period and saving the total project cost. The Working Principle of Steel Fiber Fibers reinforce in three dimensions throughout the entire concrete matrix. Fiber performance is based on the combination of the tensile strength, aspect ratio(length/diameter) and anchorage. The distributed fibers restrain micro- cracking and redistribute accumulated stress caused by applied loads and shrinkage. The sooner the crack is intercepted and its growth is inhibited, the less chance the crack will occur. FAQs of Steel Fiber What is steel fiber reinforced concrete? Fiber reinforced concrete is comprised of hydraulic cements containing fine and course aggregatea and fiber. A super-plasticizer is ofter used to enhance the mix workability. Fiber products are available in a variety of types and sizes. The underlying principle however on all fiber reinforced concrete is to provide discoutinuous reinforcement and effective crack control. How do fiber work? Fibers reinforce in three fimensions throughout the entire concrete matrix. Fiber performance is based on the combination of the tensile strength, aspect ratio(length/diameter)and anchorage. the distributed fibers resrain micro- cracking and redistribute accumulated stress caused by applied loads and shrinkage. The earlier a crack is intercepted and its growth inhibited, the less chace it will have develop. What are the types of steel fibers used in concrete ? 1.Straight 2.hooked 3.Crimped.4.Double duoform 5.ordinary duoform 6.paddied 7.enlarged ends 8.irregular 9.indented. Is there a difference between Micro and Macro Synthetic Fiber? Macro synthetic fibers are intended to carry a load and therefore, can be used to replace traditional reinforcement. Typical applicationss are: slabs on ground, shotcrete, precast and composit metal deck applications. Macro synthetic fibers are also used to eliminate both early and long term cracking. Micro fibers are generally utilized to minimize early age plastic shrinkage cracking and aggregate settlement that can occur within the first 24 hours.
