PP fiber reinforced concrete is a reinforced composite material composed of polypropylene fibers (macrofiber and microfiber), cement, aggregates, and other additives. PP fiber reinforced concrete has excellent crack resistance, bending resistance, and lightweight properties, and is widely used in concrete engineering, such as subways, airport runways, industrial floors, prefabricated panels, tunnels, and so on. Polypropylene fiber reinforced concrete has a longer service life and economic benefits than ordinary concrete.
The use of polypropylene fiber as a reinforcing material in concrete is becoming increasingly widespread. As a professional concrete fiber manufacturer, Oude Chemical Fiber is constantly researching and improving new products. Currently, the strength of polypropylene coarse fibers can reach up to 850Mpa. With continuous improvement and research and development, the mechanical properties of modified polypropylene fibers will be further improved.The widespread application of polypropylene fiber reinforced concrete mainly benefits from the properties of polypropylene fibers.
Firstly, as polypropylene fiber is the lightest synthetic fiber in terms of specific gravity, it has the advantage of having a larger number of single fibers with the same weight and diameter. Therefore, it can reduce the usage of products and lower economic costs.
Secondly, the raw materials for producing polypropylene fibers are extremely abundant, therefore, they have a low price, which also saves costs for the project.
Thirdly, polypropylene fibers have excellent alkali resistance, which allows them to withstand corrosion for up to a hundred years in alkaline concrete without affecting their own performance. Compared to the 20-year lifespan of steel bars or steel fibers, this greatly increases the service life of concrete and improves its economic benefits.
Fourthly, polypropylene fibers have good plasticity and can be modified through other products to improve their mechanical properties and shape. The strength of modified polypropylene coarse fibers can be greatly enhanced.
Polypropylene fiber reinforced concrete, as a type of fiber-reinforced concrete, has excellent crack resistance, peel resistance, fatigue resistance, and temperature resistance. With the development of technology and continuous practice, the application space of polypropylene fiber reinforced concrete will be even broader in the future.
