Polypropylene Fiber of Construction Chemical

Polypropylene Fiber of Construction Chemical for increasing strength

PP Fiber:

PP Fiber with polypropylene as its raw material, this fiber was produced by special technology. The products appear net-like structure with many fiber monofilaments connected.

When the fiber is put into the concrete, the horizontal structure in fiber monofilament can be destroyed in the course of stirring owing to friction and rubbing, and the fiber monofilament or net-like structure will fully stretch, thus the concrete is reinforced by a great number of polypropylene fibers.

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 for 5-10 years.
B). The walls of tunnels, mines, roofs and reservoir projects with special construction. When using spray technology in concrete construction, the PP fiber added into the concrete can effectively decrease the spray concrete's deformation rate of the walls less than 8% and that of the roof less than 12%, and also can reduce the friction. It can improve the constructing efficiency and working environment and popularize the spray technology.
C). River courses and dams, etc. The PP fiber 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 fiber can greatly strengthen the concrete's spurt resistance and heighten these projects' safety and lengthen their life 
pp fiber for motor 

it is a fiber with 4shapes mixing with concrete to reinforce the strength of concrete and crack resist.

  1. A. Length: for mortar,<12mm; for concrete:>12mm.

  2. B. Compounding Amount: for resisting the common cracks on surface, 0.9kg/m3 fibers to cement mortar are enough.

  3. C. Stirring Requirement: the proportion of cement, sand and aggregate is no need to be changed. Put cement, aggregate, additive and fiber together, then stir after adding enough water and time for stirring can be prolonged for 2-3 minutes in order to make the compound mix completely. Also it can be mixed even with cement and other aggregates in advance, stirring by adding water at worksite before constructing.

  4. D. Package: common 0.9 or 1kg per bag. May be modified with customer’s requirement.
