Synthetic macro fiber is a type of polymer fiber, also known as polypropylene imitation steel fiber, Polypropylene macro fibers, or composite fiber. Since the mid-19th century, it has been widely researched and promoted, and has become a research hotspot in the field of reinforced concrete. As a relatively traditional reinforcing fiber, Hooked end steel fiber plays an irreplaceable role due to its high strength and high modulus. Synthetic macro fibers and steel fibers, as reinforced fibers in concrete, are widely used in various engineering projects. There are similarities and differences between the two.
Steel fibers : 2D state in concrete.
Synthetic macro fibers :3D state in concrete.
Steel fibers: Crack control is limited. It has little impact on microcracks.
Synthetic macro fibers :The crack control is very high,minimize concrete cracks, including corner cracks, to the greatest extent possible.
Steel fibers : It has no effect on wear resistance.
Synthetic macro fibers : Increase surface wear resistance by keeping the concrete mixture together
Steel fibers :Its contribution to combating impact is limited.
Synthetic macro fibers : It perfectly improves the impact resistance of concrete.
Steel fibers : It lacks acid resistance. Limited alkali resistance. Corrosion over time.
Synthetic macro fibers :Very high alkali and acid resistance. Due to its structure (polypropylene), it does not corrode.
Steel fibers : The lifespan of buildings is limited.
Synthetic fibers : It can greatly improve the service life of concrete
Steel fibers : Low durability.
Synthetic fibers : Increase the durability of concrete.
Steel fibers: It requires iron craftsmanship. It can create risks during childbirth and waste time in practice.
Synthetic fibers : No labor required. Provide up to 50% application speed while saving time.
Steel fibers : It has no impact on isolation.
Synthetic fibers : Reduce isolation. It keeps the concrete components together
