SDS Steel Fiber

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.
