PP Mesh Fiber For Concrete

PP Mesh Fiber For Concrete

Polypropylene mesh fibers are short fibers with a reticular structure, which are formed by processing polypropylene through a special process.The tensile strength of polypropylene mesh fibers can reach 300-600 MPa, with a high elastic modulus, which can effectively limit the expansion of concrete cracks.The elongation rate is low (about 15%-25%), ensuring stable mechanical properties under load. The mesh structure is prone to disperse into single filaments during the mixing process, evenly distributed in the concrete, avoiding the phenomenon of agglomeration.

Parameter

PP mesh fiber concrete fiber feature:

 Reinforced Functions to Concrete: compared with steel fiber, full-dispersed polypropylene fiber has advantages in its thinness, large amount, non-water absorbency, strong acid & alkali resistance and similar elastic modulus with that of concrete.

The reinforced functions run as follows：

◆Increase seepage resistance    

◆Prolong endurance    

◆Improve steel protection

◆Increase cracking resistance   

◆Increase fire resistance  

◆Strengthen spurt & fatigue

◆Improve tensile, bending & folding strength             

◆Improve plastic deformity  

◆Strong acid & alkali resistance and good endurance

Application

- Projects like concrete road, bridge, airport road and factory floor which strictly require cracking resistance.

- The wall of tunnels, mines, roofs and reservoir projects with special construction.

- River courses and dams, etc.

- Dock banks and piers, etc.
