Concrete Reinforcing Fibers Polypropylene Fibers

Traditional concrete is prone to cracks when facing temperature changes and plastic shrinkage, thereby affecting the durability and safety of the structure. However, polypropylene fibers(PP micro fibers,PP macro fibers or PP mesh fibers), as concrete reinforcing fibers, can effectively address these issues and safeguard the quality of your project.

◆Superb crack resistance, safeguarding structural safety

Polypropylene fibers are evenly distributed in the concrete, forming a three-dimensional random support system. During the early plastic stage of the concrete, when water evaporates rapidly and causes shrinkage stress, the fibers can effectively disperse the stress and prevent the formation and expansion of micro-cracks.

◆Efficient anti-seepage, extending service life

The addition of polypropylene fibers makes the internal structure of the concrete more compact. The tiny fiber network formed by the fibers in the concrete effectively blocks the channels for water and harmful substances to penetrate. Whether it is the waterproofing requirements of underground projects or the long-term water erosion of structures such as bridges and tunnels, polypropylene fibers can significantly enhance the anti-seepage performance of the concrete, reduce the corrosion risk of harmful substances such as chloride ions and sulfates to steel bars, and significantly extend the service life of the project.

◆Enhanced toughness, improved impact resistance

When subjected to external force impact, polypropylene fibers can absorb energy, enhancing the toughness of the concrete. The friction and adhesion between the fibers and the concrete matrix prevent the concrete from instantly cracking but maintain a certain integrity during failure. This characteristic is particularly prominent in projects with high requirements for wear resistance and impact resistance, such as airport runways and industrial floors, effectively reducing the damage to concrete caused by frequent load impact. Polypropylene fibers, as an enhancing fiber, are widely used.
