Research on the Durability of Polypropylene Fiber Concrete
In order to study the durability of Polypropylene fiber concrete, indoor artificial methods were used to simulate dry-wet cycle and deicer-frost damage. The results indicated that amounts of polypropylene fibers increase the flexural strength of concrete slightly. The chloride penetration depth increased as the cycles of dry-wet was increased, adding 0.1% PPF into concrete have the prefect resistance of Cl- penetration. Under salt freezing cycle, the deicer-scaling resistance of concrete is reduced by the addition of Polypropylene fiber. The corner of concrete has the largest Cl- penetration area.
