SDS Steel Fiber
There are many types of steel fibre used in concrete. The steel fiber for concrete reinforcement is a new kind of metal material, in order to enhance concrete with metal fiber and shotcrete in its hardened state. Tengzhou SDS steel fiber 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 floors, highways, high-speed rail, bridges, airports, tunnels, water conservancy, electric power, municipal engineering, etc. The company has passed ISO9001 certification, and its products are exported to Southeast Asia, Europe, America and etc. Welcome to contact us for more information about steel fibers for concrete reinforcement.
Steel Fibre Types
Loose Hooked End Steel Fiber
It is used in industrial floors and etc.
Micro Copper Coated Steel Fiber
It is widely used in Reactive Powder Concrete. The raw materials used in the production of RPC cover mainly include: 425R ordinary portland cement, quartz sand, steel fiber, micro-silica powder, slag powder, RPC special additive, clear water and etc.
Glued Hooked End Steel Fiber
It is widely used in industrial floors, parking lot, road pavement 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 steel fibre reinforcement 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 of metal fibers for concrete due to the low steel fibre cost.
Under the same strength requirement, metal fibers for concrete 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 steel fibre cost.
The Working Principle of Steel Fiber
Steel fibers for concrete reinforcement reinforce in three dimensions throughout the entire concrete matrix. Metal fiber concrete performance is based on the combination of the tensile strength, aspect ratio(length/diameter) and anchorage. The distributed steel fiber reinforcement 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.
