Polypropylene plastic steel fiber

Polypropylene plastic steel fiber is made of polypropylene and polyethylene as the main raw materials and refined by a special production process. It has a rough surface, a clear outline, good dispersibility and cement matrix products. It has both the functions of steel fiber and the advantages of synthetic fiber. It is mainly used to replace welded metal grids and steel fibers in concrete panel structures.

Application range:

Imitation steel fiber is widely used in pavements, curbs, ordinary concrete panels, bridge engineering floors, airport runways, aprons, concrete precast panels, pipes, various tunnel construction, roofs, parking lots, water conservancy projects, container terminals and various concrete buildings.

Main functions

High tensile strength.

Strong acid and alkali resistance.

Possessing the functions of steel bars and steel fibers.

Construction suggestions:

Dosage: 3-9Kg per cubic meter of concrete

Length: 30mm-50mm for general crack prevention and reinforcement; 20mm-30mm for sprayed concrete.

Feeding and mixing process: First add crushed stone, then plastic steel fiber, then add sand and mix to fully disperse the plastic steel fiber, then add cement and water according to the conventional process. It can also be constructed in the order of kneading and input according to the conventional process, but the mixing time should be appropriately extended so that the plastic steel fiber is evenly dispersed.
