1. Ration design of the fiber concrete:
Generally the recommended amount to add to the concrete is more than 2.7kg per m3(volume ratio is 0.3%), reinforcement adding amount is 5.5kg, Compared with adding 47kg of steel fibre, 5.4kg polymer fiber has the same volume ratio to the concrete.
 
2. Length: 54mm for common crack-resistant requirement.
 
3. Matching Ratio: Usually, it is no need to Change the matching ratio of the concrete. Considering the requirement of fissure-resistant, the polymer fiber is recommend to combine with the PP fiber mesh form with the volume ratio of 1:1 (0.9kg fiber-mesh to per m3 of cement concrete).
 
4. Mixer Adoption: Double-axle horizontal compelling mixer is priority.
 
5. Mixing process: Stones, fiber and sand are putted into the blender. After mixing for 2 minutes, spread out the fiber, then add cement and water and mix normally. The added material can also be added as ordinary concrete, but the mixing time should be appropriately extended, so that the fiber is completely mixed.

 6. Shaping & Maintenance: There is no special requirement, may along the vibrating time for 30s, The maintenance of the fiber concrete should be done same as the normal concrete.
