Polypropylene monofilament fibers are high-strength, bundle-type monofilament fibers made primarily from polypropylene through a specialized manufacturing process. They are commonly added to concrete or mortar to suppress plastic shrinkage cracks in cement mortar and concrete before curing, enhancing the toughness of the cement mortar and concrete. This improves the intrinsic quality of the materials, reduces maintenance costs, and extends the service life of the project.
Characteristics and Functions
• Easy Dispersion: Polypropylene monofilament fibers disperse easily in mortar or concrete without clumping, effectively ensuring crack resistance.
• Convenience in Use: There is no need to alter the mortar mix ratio; simply add the fibers into the mortar mixture, mix briefly after adding water.
• Excellent Economic Performance: The equivalent diameter of polypropylene monofilament fibers is only φ 0.02-0.03 mm, giving them a high ratio of surface area to diameter. This allows for reduced fiber usage (approximately 0.6-0.9 kg/m³) while maintaining crack resistance.
• Ease of Plastering: The fibers are uniformly distributed throughout the mortar, making plastering easier and enhancing the bond strength between the surface and the base layer.
• Stable Chemical Properties: Polypropylene fibers exhibit strong resistance to acids and alkalis, making them suitable for use in any engineering project.
