Polypropylene Fiber-Mesh is a type of synthetic fiber reinforcement material used in concrete and cement-based applications to improve the overall strength, durability, and crack resistance of the concrete. It is made from polypropylene, a strong and lightweight polymer that is resistant to chemicals and biological degradation.

How PP Fiber Mesh Functions
The fiber-mesh is typically added to the concrete mix during the mixing process. The fibers are uniformly dispersed throughout the concrete, creating a three-dimensional network that helps distribute stresses and prevent crack formation. The presence of the fibers also enhances the cohesion and tensile strength of the concrete, making it more resistant to cracking caused by shrinkage, temperature changes, and external forces.

Polypropylene Fiber-Mesh offers several advantages in concrete applications:
Improving the constructing efficiency and working environment: When using spray technology in concrete construction, the polypropylene fiber added into the concrete can effectively decrease the spray concrete's deformation rate of the walls less than 8% and that of the roof less than 12%, and also can reduce the friction.

Crack Control: The addition of fibers helps control and minimize the formation and propagation of cracks in the concrete. This is especially beneficial in large concrete structures or slabs, where cracking can lead to reduced durability and structural integrity.

Impact and Abrasion Resistance: The fibers enhance the concrete's ability to withstand impact and abrasion, making it suitable for areas subject to heavy traffic or mechanical stress.

Freeze-Thaw Durability: Concrete containing Fiber-Mesh exhibits improved resistance to damage caused by freeze-thaw cycles, which is essential in cold climates.

Reduced Plastic Shrinkage Cracking: During the initial curing stage, concrete is prone to plastic shrinkage cracking. The presence of fibers mitigates this problem and provides early-age crack control.

Increased Toughness: The fiber-mesh imparts toughness to the concrete, ensuring it can better withstand localized stresses and loads.

Applications
Polypropylene Fiber-Mesh is commonly used in a variety of concrete applications, including residential and commercial construction, industrial flooring, precast elements, shotcrete, and overlays;
The walls of tunnels, mines, roofs and reservoir projects with special construction;
Military defense works, dock banks and piers, etc.
