Product Details

During the concrete mixing process, the three-dimensional cross-linked structure of the reticular fibers gradually dissociates with the mixing direction, and the horizontal arrangement of its monofilaments undergoes dynamic reorganization due to the shear friction effect. With the continuous input of mechanical energy, the mesh fiber achieves controllable dispersion through the friction-tensile coupling effect: on the one hand, the monofilaments after the dissociation of the reticular fibers form multi-directionally distributed micro-reinforcing units in the matrix; On the other hand, the residual reticular structure fragments are reconstructed into a spatial three-dimensional support system within the plastic matrix. This multi-scale synergistic effect enables polypropylene fibers to not only suppress the propagation of microcracks through the monofilament bridging mechanism, but also enhance the overall toughness of the material by relying on the reorganized network structure. Ultimately, the hierarchical optimization of the crack resistance performance of concrete is achieved through the composite reinforcement effect of the fiber network and monofilament.

Parameter

Feature

As a new type concrete-strengthening fiber, it becomes a new popular subject in the field of fiber concrete research and application 

after glass fiber and steel fiber.

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.

- Military defense works, dock banks and piers, etc.
