Polypropylene fiber construction process
Polypropylene fiber construction process use steps: polypropylene fiber content is generally range: the amount of steel fiber per m 3 of concrete ranges from 0.6 to 0.9 kg. Reinforced, toughened, crack resistant, impervious, high strength concrete or shotcrete can be increased to 0.9~1.8 kg.

1. According to the amount of concrete mixed each time, the weight of each added fiber is correctly measured according to the mixing ratio requirement (or recommended dosage).
2. After the sand and gravel is prepared, add the fiber. A forced blender is recommended.
3, the aggregate together with the fiber into the mixer, but care should be taken to ensure that the fiber is added between the aggregate, dry mix for about 30 seconds, add cement and water, wet mix for about 30 seconds, so that the fiber is fully dispersed.
4. Randomly sample after the completion of the agitation. If the fiber has been uniformly dispersed into monofilament, the concrete can be put into use. If there is still bundled fiber, the mixing time can be extended for 20-30 seconds.
5. The fiber-added concrete is identical to the ordinary concrete construction and maintenance process.
6. Mortar is recommended to use monofilament fiber. The amount of mortar per square is: 0.9-1.2kg
It is recommended to use reticular fiber for concrete. The amount of concrete per square is: 0.9-1.8kg
