How Polypropylene Microfibers Improve Concrete Performance
During mixing, HPM® PP disperses uniformly to form a multidirectional polypropylene reinforcement network, effectively:
-
interrupting early-age crack formation
-
reducing plastic shrinkage, bleeding, and segregation
-
enhancing cohesiveness in concrete & mortar
-
improving surface durability after curing
This makes it ideal for pp fiber concrete applications requiring high finish quality and crack control performance.

Need Better Crack Control Than Polypropylene Fiber?
Polypropylene fiber is widely used for basic crack control in concrete, especially for plastic shrinkage. It is a practical and cost-effective solution in most standard applications.
However, for projects requiring reduced visible cracking, higher durability, and long-term performance, its effect after hardening can be limited.

Upgrade to Rimix™ NanoRebar
Rimix™ NanoRebar is an advanced micro fiber designed for more efficient crack control.
Its ultra-fine diameter creates significantly more fibers per m³, increasing the chance of stopping micro-cracks early.
With higher strength and modulus, it works in both the plastic and hardened stages, helping improve crack resistance, toughness, and overall concrete reliability — not just early shrinkage control.

FAQ
Monofilament polypropylene fiber is used to control plastic shrinkage cracks, reduce settlement cracking, and improve durability in concrete, mortar, and plaster.
Typical dosage is 0.6–1.2 kg/m³ depending on slab thickness, temperature, and project requirements.
PP microfibers control early-age cracking but do not replace structural reinforcement. They can reduce the need for light mesh in non-structural applications.
