pp fiber is also called engineering fiber, concrete fiber, anti-cracking fiber, synthetic fiber or plastic fiber.
Mixing pp fiber into concrete or mortar can control microcrack , which caused by plasticity contraction, air shrinkage or temperature change. 

Junchi® Fibre is a monofilament polypropylene fibre for use in concrete to reduce the incidence of plastic shrinkage cracking. Junchi® Fibre increases the strain capacity of the fresh concrete therefore reducing plastic cracking.

pp fiber construction technology:

1.According to the volume of concrete, in accordance with the requirements for mixture ratio (or suggested dosage) to calculate fiber dosage.

2.After building stones of sand is ready, add the pp fiber. Recommend to use the forced mixer.

3.Add the pp fiber and aggregate into the mixer.But notice: fiber must been added between the aggregate,dry mixing 30s,add cement and water,wet mixture 30s, in order to make the fiber dispersed adequately.

4.Stir after the completion of the random sampling, such as fiber has evenly dispersed into monofilament, concrete can be put into use, if you still have bunch of fiber is extended mixing time 20-30 seconds, then concrete can be used.

5.Add fiber concrete with normal concrete construction and maintenance process is exactly the same.
