Polypropylene fibers

Polypropylene fibers


In our country, flooding occurs in almost all concrete constructions, which is usually easily solved by spraying cement on the concrete surface. However, this solution leads to the formation of a very weak surface with a high ratio of water to cement, which is easily separated from the concrete and has very low abrasion resistance. Cracks make the surface look bad if exposed. The application of RW Fiber PP prevents such a phenomenon from occurring and creates a solid surface. In addition, the use of RW Fiber PP causes the water to cement ratio to remain constant throughout the thickness of the member and the hydration of the cement to continue. With the above explanations, it can be concluded that the use of RW Fiber PP leads to a suitable surface with high abrasion resistance and also reduces the permeability of concrete and minimizes the penetration of corrosive agents into the concrete and increases the durability of concrete. This in areas such as the southern and northern coasts of the country prevents the loss of national capital. RW Fiber PP complies with ASTM C1116 standard.


For the production of ductile concrete
Production of concrete with high impact and abrasion resistance
Production of fireproof concrete
In ready-mixed concrete and production of prefabricated parts
In addition to application in concrete and cement, it is also used in gypsum and gypsum prefabricated panels.
In the production of cement sheets (Iranite)
In the manufacture of wall coverings (Romalin)

Consumption benefits:

• Makes concrete durable in harsh environmental conditions.
• Significantly reduces cracking.
• Prevents wastage of large capital due to corrosion of reinforcement and concrete failure.
• It is a suitable alternative to thermal reinforcement.
• Prevent dehydration and aid in hydration
• Reduce permeability and increase concrete resistance against melting and freezing cycles
• Increase compressive strength and increase wear resistance

Consumption rate:

The average consumption of RW Fiber PP varies from 0.6 to 3 kg per cubic meter of concrete, depending on the performance of the mortar to replace thermal reinforcement and prevent premature cracking or shrinkage and proper and optimal performance.

The average consumption (for example, slabs) is about one kilogram per cubic meter. In prefabricated parts using slurry infiltrated system, more RW Fiber PP must be used to achieve the desired goal (desired flexural strength).

Method of Use:

RW Fiber PP can be added to concrete at any time. Usually mix RW Fiber PP with aggregates first and then add water. You can mix RW Fiber PP with mixing water and then add this water to the dry mortar, in which case you should continue stirring for 3 to 4 minutes to achieve a homogeneous and homogeneous mixture. If ready-mixed concrete is used, RW Fiber PP can be poured gradually into the mixer and stirring at high speed should be continued until you are sure that the RW Fiber PP is fully spread inside the concrete.

Note: Note that RW Fiber PP is hydrophobic and its water absorption percentage is zero, so never add water to increase the flow of concrete.
