What is the most striking feature of PP staple fiber in engineering construction?

PP short fiber has good chemical stability, safety, non-toxicity, acid and alkali resistance, anti-magnetic and anti-rust, strong bonding with cement, no change of original mix ratio, no special requirements for construction. With the simple construction of PP short fiber, the original ratio can be changed without special requirements. The PP short fiber produced by Boao is often used in many large-scale projects and has won unanimous favorable comments from users.

The use of PP staple fiber products can significantly improve the impact resistance, performance and wear resistance of concrete. Although PP short fiber has low rigidity and poor ability to transmit load interception, it can absorb impact energy, effectively reduce cracks, enhance the continuity of dielectric materials, and reduce the local stress phenomenon caused by the shock wave being blocked, thus greatly improving concrete. Impact resistance and toughness.

PP short fibers also improve the frost resistance of concrete. The addition of PP short fibers in concrete can alleviate the internal stress of concrete caused by temperature changes and prevent the expansion of temperature cracks. At the same time, the improvement of concrete anti-freezing ability is also beneficial to the improvement of its anti-freezing ability. Practice and research have shown that the addition of PP short fibers in concrete can be used as an effective concrete temperature compensation and crack resistance.
