Introduction of Milling Steel Fiber

Milled steel fiber is a fiber milled from thick steel plates or ingots. The overall surface is wavy and the cross section is crescent-shaped.

Product function of Milling Steel Fiber

1. Excellent wear resistance and durability, higher fatigue endurance limit. High ductility and impact resistance.

2. Good dispersion, steel fiber will not ball up in concrete and is evenly distributed.

3. Improve the mechanical properties of concrete such as tensile, bending and shear resistance.

4. The rough and clean surface of steel fiber can be firmly combined with the cement paste in concrete.

5 Compared with traditional reinforced concrete, steel fiber concrete is directly constructed and seamlessly connected to large laser leveling equipment, saving costs.

6. The construction process is simpler, and the construction period is greatly shortened compared to the steel bar solution.

Usage Method of Milling Steel Fiber

Construction technical requirements:

1. The cement grade shall not be less than 425. The water-cement ratio shall not be greater than 0.5.

2. The diameter length of coarse aggregate should not exceed 2/3 of the length of steel fiber.

3. The volume of steel fiber in steel fiber concrete should not be less than 0.5%, generally between 0.5-3%, and 1.5%–2.5% is recommended; that is, the dosage range of each cubic meter of concrete is: 5-30kg, and 15-25kg is recommended.

4. Steel fiber concrete shall not be used for blocking, and sand and chloride salt are strictly prohibited.

5. In addition to the above provisions, other materials used in steel fiber concrete shall comply with the provisions of the current specifications on the raw materials used for reinforced concrete.

6. The consistency of steel fiber concrete can be determined by referring to the consistency required for ordinary concrete in similar projects. Its slump value can be smaller than the corresponding ordinary concrete requirement.

7. When the steel fiber concrete cushion layer and surface layer with a flat-head joint structure does not have a foundation reinforcement layer such as ash soil under the cushion layer and meets the following conditions at the same time:

a. The thickness of the pre-potential layer and surface layer is not greater than 130mm.

b. The thickness of the foundation reinforcement layer is greater than the thickness of the cushion layer. Its thickness can be multiplied by the reduction factor of 0.75, but shall not be less than 50mm

Material requirements:

Steel fiber and coarse aggregate → stir for 30 seconds → add sand and cement → stir for 30 seconds → add water → stir for 3 minutes

Compacting:

1. When pouring steel fiber concrete, mix and use it, pour continuously, and do not throw away the construction joints before the partition joints. It should be vibrated and compacted during pouring.

2. Surface finishing, embossed steel fiber concrete has the characteristics of fine coarse aggregate, large sand rate, and random fiber distribution. It is smoothed mechanically to prevent fiber exposure. The embossing process of the embossing machine can also avoid the phenomenon of fiber exposure caused by hair pulling. After 24 hours, it should be maintained in time according to routine. In summer, it should be covered with straw bags and the like, and in winter, it should be kept warm.

FAQs of Milling Steel Fiber

 What are the Benefits of Using Milling Steel Fibers in Concrete?

Using milling steel fibers in concrete offers several advantages:

• Improved Durability: The fibers increase the concrete’s resistance to cracking, thus enhancing the durability of the structure.
• Increased Toughness: They improve the concrete’s ability to withstand shock and impact loads.
• Flexural Strength: The fibers significantly increase the flexural strength of the concrete, making it less prone to bending under load.
• Reduced Shrinkage Cracking: By providing internal support, they can reduce the formation of shrinkage cracks during the curing process.

How Are Milling Steel Fibers Different from Other Types of Steel Fibers?

Milling steel fibers differ primarily in their manufacturing process and physical characteristics. For example, they might be more uniform in shape and size compared to other types of fibers, which could be cut from different materials or processes. Additionally, milling steel fibers might have specific geometries that enhance their performance in concrete.

How Are Milling Steel Fibers Used in Construction?

Milling steel fibers are added to the concrete mix during the batching process. They are mixed thoroughly to ensure even distribution throughout the concrete. Once the concrete sets, the fibers provide additional reinforcement within the matrix.

Can Milling Steel Fibers Replace Traditional Reinforcement?

In some applications, milling steel fibers can partially or fully replace traditional reinforcement such as rebar. This is particularly true for applications where the addition of fibers can provide sufficient reinforcement for the intended loads and service conditions. However, each application must be evaluated on a case-by-case basis, and engineering judgment is necessary.
