Fibrillated PP Microfiber: Advanced Concrete Reinforcement

Microfibre PP fibrée is a synthetic polypropylene fiber designed to reinforce concrete. It helps control plastic shrinkage cracking, reduces bleeding, and enhances the overall durability of concrete structures.

These fibers are typically added during the mixing process. It’s recommended to mix for 5 to 6 minutes at high speed after adding the fibers to ensure uniform distribution throughout the concrete.

While Microfibre PP fibrée enhances certain properties of concrete, such as reducing plastic shrinkage cracking, it is not a substitute for structural steel reinforcement. It’s best used alongside traditional reinforcement methods to improve overall performance.

The typical dosage ranges from 0.6 to 0.9 kg per cubic meter of concrete, depending on the specific application and desired performance characteristics. Consulting with a concrete specialist can help determine the optimal amount for your project.

Generally, incorporating Microfibre PP fibrée does not adversely affect the workability of concrete. However, it’s important to ensure proper mixing to achieve uniform fiber distribution, which helps maintain the desired workability.
