Concrete is a material of a high compressive but around ten times smaller tensile strength. Furthermore, it is characterized by a brittle behavior and does not allow transferring stresses after cracking. In order to avoid brittle failure and improve mechanical properties, it is possible to add fibers to the concrete mix. This creates fiber reinforced concrete (FRC) which is a cementitious composite material with a dispersed reinforcement in a form of fibers, e.g. steel, polymer, polypropylene, glass, carbon, and others.
Fiber reinforced concrete is a cementitious composite material with a dispersed reinforcement in a form of fibers. Polypropylene fibers can be divided into microfibers and macrofibers depending on their length and the function that they perform in the concrete.
Macro synthetic fibers are typically used in structural concrete as a replacement for nominal bar or fabric reinforcement; they do not replace structural steel but macro synthetic fibers can be used to provide the concrete with significant post-cracking capacity.

Benefits:
Lightweight reinforcement;
Superior crack control;
Enhanced durability;
Post-cracking capacity.
Easily added to concrete mixture at any time
Applications
Shotcrete, concrete projects, such as foundations, pavements, bridges, mines, and water conservancy projects.
Macro PP (Polypropylene) fibers are synthetic fibers that are commonly used in concrete for various purposes. They are typically added to the concrete mix to improve its performance in several ways. Here are some of the applications and functions of macro PP fibers in concrete:

Crack Control: One of the primary functions of macro PP fibers is to control cracking in concrete. These fibers help to distribute and reduce the width and spacing of cracks that can occur due to drying shrinkage, temperature changes, or other factors. This results in improved durability and appearance of the concrete surface.

Impact Resistance: Macro PP fibers can enhance the impact resistance of concrete. This makes it suitable for applications where the concrete may be subject to impact loads, such as industrial floors, pavements, and precast concrete elements.

Improvement in Toughness: These fibers increase the toughness of concrete, which is essential for structures that need to withstand dynamic loads or severe loading conditions. This toughness helps in preventing sudden and catastrophic failure.

Reduced Plastic Shrinkage Cracking: In fresh concrete, macro PP fibers can help reduce plastic shrinkage cracking, which often occurs due to rapid moisture loss at the surface during hot or windy conditions. The fibers provide additional reinforcement during the early stages of concrete curing.

Fire Resistance: Macro PP fibers can enhance the fire resistance of concrete. They melt at high temperatures, creating small channels or voids within the concrete, which can help release internal pressure and reduce spalling during a fire.

Easier Pumping and Placing: The addition of macro PP fibers can improve the workability of concrete, making it easier to pump and place. This can be especially beneficial in large construction projects.

Abrasion Resistance: For applications where concrete is exposed to abrasion, such as industrial floors, the inclusion of macro PP fibers can improve the resistance of the concrete surface to wear and tear.

Reduced Maintenance: By reducing the likelihood of cracking and improving overall durability, macro PP fibers can lead to reduced maintenance costs for concrete structures over their lifespan.

Shrinkage Control: These fibers can help control both plastic and drying shrinkage in concrete, which is essential for maintaining the integrity of the structure and preventing cracking.

Improved Durability: Overall, the use of macro PP fibers can significantly improve the long-term durability of concrete structures, extending their service life and reducing the need for repairs.
