POLYPROPYLENE FIBRE-MESH (PP FIBRE-MESH FORM)
Properties:
With polypropylene as its raw material, this fibre was produced by special technology. The products
appear net-like in structure with many fibre monofilaments connected. When the fibre is put into the
concrete, the horizontal structure in fibre monofilament can be destroyed in the course of stirring owing
to friction and rubbing, and the fibre monofilament or net-like structure will fully stretch, thus the
concrete is reinforced by a great number of polypropylene fibres (more than 7 million pieces per sqm).
|
|
Applications:
As a new type concrete-strengthening fibre, it becomes a new popular subject in the field of fibre concrete research and application after glass fibre and steel fibre.
1. Reinforced Functions to concrete: compared with steel fibre, full-dispersed polypropylene fibre 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 follow:
• 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
2. Suitable fields for Polypropylene Fibre-Mesh:
A). Projects like concrete road, bridge, airport road and factory floor which strictly require cracking resistance. The life span of these projects will be lengthened.
B). The walls of tunnels, mines, roofs and reservoir projects with special construction. When using spray technology in concrete construction, the polypropylene
fibre added into the concrete can effectively decrease the spray concrete's deformation rate of the walls to less than 8% and that of the roof less than
12%, and also can reduce the friction. It can improve the construction efficiency and working environment and popularize the spray technology.
C). River courses and dams, etc. The polypropylene fibre can improve concrete's resistance to crack and squirt and wear to lengthen projects' life span.
D). Military defense works, dock banks and piers, etc. This fibre can greatly strengthen the concrete's spurt resistance and heighten these projects' safety and lengthen life span.
