Michem-Polypropylene-Synthetic-Fiber

Fiber for Concrete Reinforcement and Crack Control

Michem Chemical is a professional fiber for concrete supplier, providing high-performance reinforcement fibers for ready-mix concrete, precast concrete, shotcrete, and infrastructure projects.

Concrete fibers are widely used to improve:

By incorporating fiber for concrete, manufacturers and contractors can reduce cracking, improve mechanical properties, and enhance long-term durability of concrete structures.

What Is Fiber for Concrete?

Fiber for concrete refers to synthetic or structural fibers added to concrete mixtures to enhance mechanical performance and durability.

Unlike traditional steel reinforcement, concrete fibers are evenly distributed throughout the mix, creating a three-dimensional reinforcement network that:

  • Controls plastic shrinkage cracking
  • Reduces micro-cracks
  • Improves toughness
  • Enhances post-crack performance

Key Benefits of Using Fiber in Concrete

By choosing right products, you can optimize crack resistance, toughness, and durability across a wide range of concrete projects.

Crack Control

One of the primary functions of concrete fiber is to reduce plastic shrinkage cracks and micro-cracks during curing.

Improved Tensile Strength

Fibers enhance tensile and flexural strength, improving structural integrity.

Enhanced Impact Resistance

Fiber-reinforced concrete performs better under dynamic and impact loads.

Increased Durability

Concrete fibers reduce permeability and improve freeze-thaw resistance.

Reduced Steel Reinforcement

Structural synthetic fibers can partially replace steel mesh in slabs and pavements.

Cost-Effective Reinforcement Solution

Compared to traditional reinforcement systems, fiber for concrete can reduce labor time and installation costs.

Types of Fiber for Concrete

Polypropylene Micro Fiber

Whether for industrial floors, precast elements, repair mortars or general concrete reinforcement, TenaBrix provides not only this microfiber but also a full range of fiber solutions to meet diverse construction needs.

Polypropylene Macro Fiber

Macro Synthetic Fibers is high quality polypropylene in large structure of fibers, produced by special molding process and surface modification to increase toughness of concrete.

Polypropylene Fibrillated Fiber

 Synthetic Fibers for Cement Concrete and Mortar and other national and industrial standards. With stable performance and strong adaptability, it is the preferred material for enhancing crack resistance in concrete engineering.

Twisted Macro Fiber

Twisted fibers are 3x more effective at controlling plastic shrinkage cracking than standard straight fibers—making them ideal for high-stress projects like precast components, tunnels, and industrial floors.

Polyacrylonitrile Fiber(PAN)

PAN fiber outperforms most synthetic fibers in long-term durability, with a 25-year service life in concrete structures compared to 10-15 years for standard PP fiber. 

Cellulose Fiber

Cellulose fiber reduces concrete plastic shrinkage cracking by up to 50% and enhances surface finish for decorative concrete applications.

Applications of Fiber for Concrete

Concrete Slabs

Fiber reinforcement improves crack resistance and durability in slab-on-grade construction.

Driveways and Pavements

Helps reduce surface cracking caused by shrinkage and temperature changes.
Self-Leveling Compounds

Industrial Floors

Enhances load-bearing capacity and impact resistance.

Shotcrete Applications

Provides reinforcement in tunnels, mines, and slope stabilization projects.
Architectural-Precast

Precast Concrete

Improves structural integrity and reduces cracking during transport.

Bridges and Infrastructure

Used in infrastructure projects requiring long-term durability.

How Fiber for Concrete Works?

When concrete fibers are added to the mix:

  1. They disperse evenly throughout the concrete.
  2. During hydration and curing, fibers bridge micro-cracks.
  3. Crack propagation is slowed or prevented.
  4. Structural performance and toughness increase.

This three-dimensional reinforcement mechanism improves overall durability and structural integrity.
