RW Fiber PP Polypropylene Fibers

  • In our country, concrete bleeding is a prevalent issue in nearly all construction projects involving concrete. This problem is often superficially addressed by sprinkling cement on the concrete surface. However, this approach results in the formation of a weak surface layer with a high water-to-cement ratio, which is prone to delamination and exhibits poor abrasion resistance. Additionally, bleeding leads to the formation of fine cracks, commonly referred to as "crocodile skin cracks," which can significantly detract from the aesthetic appearance of the surface if visible. The application of RW Fiber PP effectively mitigates such issues, resulting in a robust and durable surface. Furthermore, the use of RW Fiber PP ensures a consistent water-to-cement ratio throughout the concrete member, facilitating continuous cement hydration. Based on the aforementioned points, it can be concluded that RW Fiber PP enhances surface quality by providing high abrasion resistance, reducing concrete permeability, minimizing the ingress of corrosive agents, and improving the overall durability of concrete. This is particularly advantageous in regions such as the southern and northern coastal areas, where it helps prevent the wastage of national resources. RW Fiber PP complies with the ASTM C1116 standard.

Applications:
– Production of workable concrete
– Production of concrete with high impact and abrasion resistance
– Production of fire-resistant concrete
– Use in ready-mix concrete and precast concrete elements
– Applications in gypsum and prefabricated gypsum panels, in addition to concrete and cement
– Production of cement boards (Iranite)
– Construction of wall coatings (Romalin)

Benefits:
– Enhances concrete durability under harsh environmental conditions
– Significantly reduces cracking
– Prevents substantial financial losses due to reinforcement corrosion and concrete deterioration
– Serves as an effective replacement for thermal reinforcement
– Prevents bleeding and promotes proper hydration
– Reduces permeability and increases resistance to freeze-thaw cycles
– Improves compressive strength and abrasion resistance

Dosage:
The typical dosage of RW Fiber PP varies between 0.6 to 3 kg per cubic meter of concrete, depending on the desired performance for replacing thermal reinforcement and preventing early cracking or shrinkage. For instance, in slabs, the average dosage is approximately 1 kg per cubic meter. In precast elements utilizing the slurry infiltrated system, a higher dosage of RW Fiber PP is required to achieve the desired flexural strength.

Application Method:
RW Fiber PP can be added to concrete at any stage. Typically, it is first mixed with aggregates, followed by the addition of water. Alternatively, RW Fiber PP can be pre-mixed with the design water, which is then added to the dry mortar. In this case, mixing should continue for 3 to 4 minutes to ensure a uniform and homogeneous mixture. When using ready-mix concrete, RW Fiber PP should be gradually introduced into the mixer, and high-speed mixing should be maintained until the fibers are uniformly dispersed throughout the concrete.

Note:
RW Fiber PP is hydrophobic and exhibits zero water absorption. Therefore, additional water should never be added to improve concrete workability.
